A Ku-Band Dual Linear-Polarized 2×4 Microstrip Patch Subarray with a Rhombic Feed Transmission Line for Enhanced Cross-Polarization Cancellation Riyani Jana Yanti, Aditya Inzani Wahdiyat, Muzammil Jusoh, Catur Apriono Engineering Technology and Applied Science Research, 2026 Α Ku-band, dual-linear polarized, 2×4 microstrip circular patch subarray antenna with co-aligned elements and a rhombic feed transmission line to is proposed to improve cross-polarization performance, enhance link reliability, and provide a compact, single-port solution for mobile satellite terminals. This design directly addresses key limitations of existing mobile satellite antennas, including polarization mismatch and degraded performance under dynamic operating conditions. Mobile satellite systems on moving platforms, such as vehicles and emergency terminals, have difficulty maintaining polarization isolation and stable performance due to motion and varying environmental conditions. The proposed antenna is optimized for communication satellite systems, integrating with Satellite Nusantara Satu. The simulation results demonstrate good impedance matching, with an S11 of –47.43 dB at 12.55 GHz, a 659 MHz bandwidth, and a 9.28 dBi gain. However, the measured results indicate a slight frequency shift to 12.32 GHz, with an S11 of –20.51 dB, a bandwidth of 364 MHz, and a gain of 8.77 dBi, due to variations in fabrication tolerance and substrate permittivity. The subarray achieves a high Cross-Polarization Level (CPL) of more than –45 dB, confirming that the antenna is reliable for Ku-band satellite communication and provides enhanced polarization purity under continuous motion and varying environmental conditions, including vibration, temperature fluctuations, humidity, and physical obstructions.
A wide axial ratio bandwidth circularly polarized filtering antenna using two quarter-wavelength resonators and a single feedline Dwi Astuti Cahyasiwi, Fitri Yuli Zulkifli, Ashif Aminulloh Fathnan, Aditya Inzani Wahdiyat, Yus Natali, Teguh Firmansyah, Dian Widi Astuti, Eko Tjipto Rahardjo International Journal of Microwave and Wireless Technologies, 2026 This study proposes a single feedline technique that results in a wide axial ratio bandwidth (ARBw) of a circularly polarized filtering antenna. The antenna is designed to operate at 4.65 GHz. The design employed a rectangular radiator and two quarter-wavelength resonators. The two components are integrated using a single feedline and proximity coupling. The quarter-wavelength resonators excite the second mode polarization on the coupled rectangular radiator. The combination of width and length of the radiator, as well as the gap between the second resonator and radiator, equalized the two modes' e-fields’ magnitude. The design requires no additional delay circuit, for the gap between the second resonator and radiator provides both selectivity and a 90° phase shift delay. The proposed design has a wide ARBw of 10.10% and an impedance bandwidth of 9.04%. The use of two resonators results in a gain curve resembling a bandpass filter response, with a maximum gain of 7.6 dBic. The antenna is fabricated and measured to validate the proposed method, and the measurement results align well with the simulation results.
Super-wideband antenna with modified elliptical-shaped for broad spectrum capability in software-defined radio applications Fitri Yuli Zulkifli, Aditya Inzani Wahdiyat, Thooriq Maulana, Ali Hanafiah Rambe, Nurhayati Nurhayati E Prime Advances in Electrical Engineering Electronics and Energy, 2025 • Superwideband performance with 1: 85 bandwidth ratio. • Low frequency coverage from 0.42 GHz. • Excellent impedance matching, with S-parameter measurements validating its superior performance across the entire frequency range. The rapid development of wireless communication technology has driven the need for integrating multiple devices into a single platform to improve connectivity. Software-Defined Radio (SDR) stands out as a promising solution but requires antennas with an exceptionally wide bandwidth. This study introduces a super-wideband microstrip antenna designed to meet these needs, covering a frequency range of 0.42 to 40 GHz. The antenna is made using a Taconic TLY-5 substrate, known for its low dielectric loss, and has a simple printed monopole microstrip design with dimensions of 160 × 260 mm². Experimental results demonstrate that the antenna operates efficiently over a broad frequency range of 0.42 to 35.96 GHz, achieving a remarkable bandwidth ratio of 1:85. The antenna exhibits a gain exceeding 2 dBi across the entire frequency range, with a peak gain of 11 dBi, and maintains a total efficiency of over 60 % across this wide frequency spectrum. Its ability to achieve resonance at extremely low frequencies, combined with a remarkable 1:85 bandwidth ratio, significantly contributes to the novelty and impact of this work. This design demonstrates a practical and efficient solution for next-generation communication systems, combining wideband performance with compactness and ease of fabrication.
Design of a circular patch sub-array microstrip antenna with dual linear polarization for Ku-band satellite communication applications Riyani Jana Yanti, Aditya Inzani Wahdiyat, Eko Tjipto Rahardjo, Fitri Yuli Zulkifli, Catur Apriono E Prime Advances in Electrical Engineering Electronics and Energy, 2025 • A phased array antenna with dual linear polarization is designed for Ku-band. • Rhombus-shaped feed structure ensures dual polarization and precise beam control. • Simulation results achieve S11 of -48.36 dB at 12.55 GHz with a gain of 8.991 dBi. • Measurement results show a frequency shift to 12.33 GHz with S11 of 13.28 dB because of fabrication and difference in the relative permit- tivity substrate. • The design supports reduced interference and large capacity for satellite communications. A phased array antenna design is needed to address the needs of satellite communication systems with more precise beam direction levels, reduced in- terference, and significant capacity support. Antenna polarization is a crucial parameter that determines the orientation of the propagated electromagnetic wave and the maximum power generated. This research has designed dual linear polarization antennas with rhombus-shaped feed to address some of the shortcomings of previous designs, such as complex design, not compact, and difficulty matching impedance. Simulation results and S11 parameter measurements are less than −10 dB. Initial simulation results show that S11 is −48.36 dB at a frequency of 12.55 GHz with a bandwidth of 360 MHz and a gain of 8.991 dBi. The measurement results show a frequency shift to 12.33 GHz with an S11 value of −13.28 dB, a bandwidth of 310 MHz, and a gain of 7.627 dBi. The parameter shift is due to differences in the dimensions of the fabrication results and differences in the relative permittivity value of the substrate. After tuning the simulation, −22.68 dB was obtained on S11 at a frequency of 12.33 GHz with a bandwidth of 924 Mhz and a gain of 9.369 dBi. This study successfully designed and tested a compact linear dual-polarization patch sub-array antenna using a rhombus-shaped feeding technique for satellite communication receiver applications based on the S21 parameter results with maximum horizontal and vertical orientation values.
Investigation of Connector Factor in Designing a Single Element Microstrip Antenna Within the Ku-Band Spectrum Muhammad Athallah Adriansyah, Aditya Inzani Wahdiyat, Catur Apriono 2025 International Electronics Symposium Ies 2025, 2025 Antenna elements are crucial for forming phased-array antennas. Despite achieving optimal design and simulation conditions, discrepancies often occur between simulation results and real-world measurements. This requires further analysis of physical factors, such as mounting connectors, that were previously overlooked. Our research investigates single-element antennas to advance phased array antenna technology and enhance satellite systems at the Ku band frequency. We achieved an optimal design for a single-element microstrip antenna in the Ku band, with bandwidths of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$13.17-14.97 \text{GHz}$</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$10.59-13.11 \text{GHz}$</tex>. Our findings highlight the importance of considering the physical impact of connectors in both the design and simulation phases during testing. These results serve as a preliminary step for further research on phased array antennas in the Ku band.
Design and Synthesis of a Four-Element Linear Antenna Array for Ku-Band Applications Muhammad Athallah Adriansyah, Aditya Inzani Wahdiyat, Catur Apriono 2025 8th International Conference on Vocational Education and Electrical Engineering Shaping A Sustainable Future with Green Innovation and Industry Collaboration for Education and Intelligent Technology Advancements Icvee 2025, 2025 Providing array elements for dynamic beamforming techniques in a phased array system can support the development of more adaptive wireless systems. This paper focuses on antenna synthesis by determining array configuration elements to evaluate beam-steering capabilities. Using a four-element rectangular patch microstrip antenna, this study achieves beam steering and sidelobe-level suppression through the grey wolf optimizer with Nelder-Mead simplex refinement (GWO-NM) algorithm’s amplitude distribution. The results show effective main beam steering, with GWO-NM optimization significantly lowering sidelobe levels. However, grating lobes are present at an angle of 30<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">◦</sup>, which could pose interference risks. The mutual coupling indicators, S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</inf>, S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">31</inf>, and S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">41</inf>, remain consistently below −20 dB. Future work should include phase shifter components to accurately measure radiation characteristics during beam steering.

The proposed antenna employs a U-slot technique and an aperture-coupled feed to achieve dual-band functionality. The simulation results demonstrate operational frequencies of $10.9-13 \mathrm{GHz}$ and $13.9-14.72 \mathrm{GHz}$, with gains of 5.208 dBi and 3.014 dBi. The measurement results validate the simulated performance, showing the practical operation at 11.18 to 12.9 GHz and 13.97 to 14.29 GHz, with corresponding gains of 5.05 and 3.62 dBi. Although the antenna successfully achieved dual-band operation, minor frequency shifts and reduced bandwidth in the lower frequency band highlight challenges to fully meet the target specifications. These results indicate the potential of the proposed U-slot antenna for compact dual-band satellite communication applications, with future work required to address remaining discrepancies and improve performance consistency.
Bandwidth and Gain Enhancement of Wideband Slotted Patch Antennas Using Proximity-Coupled Feeding for Ku-Band Applications Muhammad Danny Naufal Syach, Aditya Inzani Wahdiyat, Catur Apriono Proceedings International Seminar on Intelligent Technology and Its Applications Isitia, 2025 This study presents the development and evaluation of a wideband slotted patch microstrip antenna designed for Ku-band satellite communication, incorporating reactive loading and proximity-coupled feeding methods. The antenna achieved a simulated operational frequency range of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$11.41-15.04 \text{GHz}$</tex>, with a bandwidth of 3.63 GHz and a reflection coefficient of -11.94 dB at 13 GHz. Measurements of the fabricated prototype revealed an operational range of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$8.8-11.84 \text{GHz}$</tex> and a bandwidth of 3.04 GHz, which were slightly narrower than simulated results due to fabrication tolerances and air gaps between substrate layers. The measured gain at the center frequency of 13 GHz reached 4.86 dB, demonstrating close agreement with simulated values and confirming the antenna's effectiveness for practical applications. Although minor deviations were observed, the proposed design proves to be a reliable and adaptable solution for wideband communication, particularly in fixed satellite services and Earth exploration. Future refinements in fabrication and assembly processes are expected to further enhance performance consistency and alignment between simulations and measurements.
Bowtie Antenna with Modification to Reduce Radiation Arm Area and Use of Parabolic Reflector to Increase Power Dissipation in Antenna Coupled Microbolometer Andrano Mario Hitipeuw, Aditya Inzani Wahdiyat, Catur Apriono Proceedings of the 2025 IEEE International Conference on Industry 4 0 Artificial Intelligence and Communications Technology Iaict 2025, 2025 Terahertz (THz) waves, ranging from 0.1 to 10 THz, possess unique properties, such as being able to penetrate nonconductive materials, making them ideal for nondestructive applications such as medical imaging and security detection. The high sensitivity of a THz waves detector is a crucial aspect in obtaining good performance from a THz system. The antenna-coupled bolometer technique is a candidate for providing a room-temperature detector and can be improved by taking advantage of the antenna design. A planar bowtie offers wideband bandwidth and easy coupling with a bolometer. This research proposes a modified bowtie antenna on the arm to centralize the electric field distribution and a parabolic reflector to improve gain and power dissipation in the bolometer. Simulations using CST Microwave Studio 2024 show that the modified antenna achieved a gain of 15.998 dBi, and, when combined with a bolometer, a maximum power dissipation of $4.13 \cdot 10^{-10}$ W. The enhanced configuration offers improved performance over standard designs, enabling practical applications in THz imaging and detection without cryogenic cooling.
