Triple Band Monopole Antenna for RFID, Energy Harvesting and Data Communication T Rahul, Devisowjanya P, K. P. Jayaram Proceedings Icnews 2024 2nd International Conference on Networking Embedded and Wireless Systems Wireless Technology Building A Digital World, 2024 A growing amount of attention has been placed on the effective use of radio frequency (RF) waves for energy harvesting integrations of RFID with wireless communication systems and Internet of Things (IoT) applications. This work investigates multi-band energy harvesting utilizing a monopole antenna, with a specific concentration on three different frequency bands. The monopole antenna provides adjustable performance in a variety of frequency ranges. The monopole antenna has remarkable properties for short-range communication and identification operations in the lower frequency band [840 – 960 MHz], devoted to NRFID (Near field radio frequency identification) deployment. The energy harvesting circuit uses the middle-frequency band [2.4 GHz], to transform the antenna’s radio frequency waves into electrical energy. This energy-collecting feature is very promising for IoT nodes, sensors, and low-power devices. A wide range of wireless communication applications are supported by the antenna's ability to transmit and receive data across long distances, as evidenced by the higher frequency band [4 - 4.7 GHz] that is set aside for data communication. The radiation pattern and the antenna's gain at frequencies of 2.4 GHz and 4.3 GHz is 3.040 dB and 3.464 dB. To evaluate the antenna's performance in RFID applications, the power conversion efficiency is calculated. With the use of a rectifier, the designed antenna has produced a 50% efficiency.
Quad-port multiservice integrated optically transparent automotive antenna for vehicular classification applications Lekha Kannappan, Sandeep Kumar Palaniswamy, Malathi Kanagasabai, Jayaram Kizhekke Pakkathillam, Sachin Kumar, et al. Scientific Reports, 2023 The demand for vehicular antennas increases in tandem with the need for multiple features in automobiles. The development of optically transparent antenna (OTA) has made it possible to deploy antennas on delicate surfaces such as glass. Earlier studies on OTA demonstrated its viability using materials such as transparent conducting oxides (TCO) and conductive polymers. A tri-band OTA is proposed in this paper for vehicular applications. The antenna operates at 1.8 GHz, 2.4 GHz and 3.39–12 GHz bands, covering automotive/wireless applications such as GSM, Bluetooth, Wi-Fi, vehicular communication and electronic toll collection. The proposed OTA is developed on soda lime glass, and the material TCO is used for the radiator and the ground plane. The antenna prototype is tested on windshield and in an anechoic chamber, the gain and efficiency are found to be greater than 1 dBi and 80%, respectively. Furthermore, a machine learning technique for vehicle classification is proposed, which could help in electronic toll collection, automatic vehicle identifier, and parking management applications. The presented algorithm achieves 80% classification accuracy with a minimum window size.
3-D twelve-port multi-service diversity antenna for automotive communications Lekha Kannappan, Sandeep Kumar Palaniswamy, Malathi Kanagasabai, Preetam Kumar, M. Gulam Nabi Alsath, et al. Scientific Reports, 2022 This paper presents a twelve-port ultra-wideband multiple-input-multiple-output (MIMO)/diversity antenna integrated with GSM and Bluetooth bands. The twelve-port antenna is constructed by arranging four elements in the horizontal plane and eight elements in the vertical plane. The antenna element, which is created using a simple rectangular monopole, exhibits a frequency range of 3.1 to 12 GHz. The additional Bluetooth and GSM bands are achieved by introducing stubs into the ground plane. The size of the MIMO antenna is 100 × 100 mm2. The antenna offers polarization diversity, with vertical and horizontal polarization in each plane. The diversity antenna has a bandwidth of 1.7–1.9 GHz, 2.35–2.55 GHz, and 3–12 GHz, the radiation efficiency of 90%, and peak gain of 2.19 dBi. The proposed antenna offers an envelope correlation coefficient of < 0.12, apparent diversity gain of > 9.9 dB, effective diversity gain of > 8.9 dB, mean effective gain of < 1 dB, and channel capacity loss of < 0.35 bits/s/Hz. Also, the MIMO antenna is tested for housing effects in order to determine its suitability for automotive applications.
Evaluation of RCS Reduction Strategies for Planar Printed C Band Tapered Slot Antennas Avanthika Velmurugan, Deeksha Venkatesan, Raajasree Chandrasekaran, Jayaram Kizhekke Pakkathillam Mysurucon 2022 2022 IEEE 2nd Mysore Sub Section International Conference, 2022 This paper presents the analytical design and radar cross-section (RCS) reduction of linear, tapered slot antenna for C band applications. The antenna was designed on an FR-4 substrate. The complete characterization of the antenna was carried out in terms of reflection coefficient, radiation pattern, antenna gain and RCS. The antenna operates over C band microwave frequencies and the centre frequency of operation is 6.7 GHz. It has been observed from the simulation that different types of metallic reduction strategies viz. rectangular cut, trapezoidal cut, cutout stripes, and semicircular cut, implemented on the reference antenna were able to provide RCS reduction. It was found that the cutout stripes technique has a minimum frequency shift of 200 MHz from the centre frequency of the reference antenna, better RCS reduction of 12dB at 6.7 GHz and preserves the radiation pattern to a large extent.
Tailoring Antenna Focal Plane Characteristics for a Compact Free-Space Microwave Complex Dielectric Permittivity Measurement Setup Jayaram Kizhekke Pakkathillam, Balamurugan T. Sivaprakasam, Jayaprakash Poojali, C. V. Krishnamurthy, Kavitha Arunachalam IEEE Transactions on Instrumentation and Measurement, 2021 This article presents a compact precision free-space microwave measurement setup with a choice of three dielectric lenses to tailor the antenna focal plane characteristics for extracting complex dielectric permittivity of small samples. Custom designed spot-focusing horn antenna pairs were used to achieve a compact setup with antenna separation distance, <inline-formula> <tex-math notation="LaTeX">${2}{f}_{l}$ </tex-math></inline-formula>:<inline-formula> <tex-math notation="LaTeX">$4{\\lambda }_{c}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$8{\\lambda }_{c}$ </tex-math></inline-formula> and focal spot size, <inline-formula> <tex-math notation="LaTeX">${f}_{s}$ </tex-math></inline-formula>:<inline-formula> <tex-math notation="LaTeX">$1{\\lambda }_{c}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$1.5{\\lambda }_{c}$ </tex-math></inline-formula>, where <inline-formula> <tex-math notation="LaTeX">${\\lambda }_{c}$ </tex-math></inline-formula> is the wavelength at center frequency. Using the compact free-space setup, relative complex permittivity (<inline-formula> <tex-math notation="LaTeX">${\\varepsilon '-j\\varepsilon ''}$ </tex-math></inline-formula>) was extracted over 8–12 GHz for low- and high-loss dielectrics with lateral dimensions, <inline-formula> <tex-math notation="LaTeX">$3.3{\\lambda }_{c}\\times 3.3{\\lambda }_{c}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$10{\\lambda }_{c}\\times 10{\\lambda }_{c}$ </tex-math></inline-formula>. For large materials under test (MUTs), i.e., <inline-formula> <tex-math notation="LaTeX">$10{\\lambda }_{c}\\times 10{\\lambda }_{c}$ </tex-math></inline-formula>, measurement accuracy in dielectric constant, <inline-formula> <tex-math notation="LaTeX">${\\Delta \\varepsilon '}$ </tex-math></inline-formula>% was <0.65% and ≤1.14% for low- and high-loss dielectrics, respectively. For smaller MUTs (<inline-formula> <tex-math notation="LaTeX">$3.3{\\lambda }_{c}\\times 3.3{\\lambda }_{c}$ </tex-math></inline-formula>), <inline-formula> <tex-math notation="LaTeX">${\\Delta \\varepsilon '}$ </tex-math></inline-formula>% was <0.89% and ≤2.29% for low- and high-loss MUTs, respectively. The error in loss tangent (<inline-formula> <tex-math notation="LaTeX">${\\Delta }\\text {tan}{\\delta }$ </tex-math></inline-formula>) varied over 0.002–0.016 and 0.015–0.056 for large (<inline-formula> <tex-math notation="LaTeX">$10{\\lambda }_{c}\\times 10{\\lambda }_{c}$ </tex-math></inline-formula>) and small MUTs (<inline-formula> <tex-math notation="LaTeX">$3.3{\\lambda }_{c}\\times 3.3{\\lambda }_{c}$ </tex-math></inline-formula>), respectively. For large MUTs, biconvex lens pair with the smallest <inline-formula> <tex-math notation="LaTeX">${f}_{s}$ </tex-math></inline-formula>(<inline-formula> <tex-math notation="LaTeX">$1{\\lambda }_{c}$ </tex-math></inline-formula>) and <inline-formula> <tex-math notation="LaTeX">${f}_{l}$ </tex-math></inline-formula>(<inline-formula> <tex-math notation="LaTeX">$4{\\lambda }_{c}$ </tex-math></inline-formula>) among the three lenses yielded the best accuracy in dielectric constant (<inline-formula> <tex-math notation="LaTeX">${\\varepsilon '}$ </tex-math></inline-formula>) due to tight field focusing at the focal plane. The plano-convex lens pair yielded the best accuracy in loss tangent (<inline-formula> <tex-math notation="LaTeX">$\\text {tan}{\\delta =\\varepsilon ''/\\varepsilon '}$ </tex-math></inline-formula>) for large MUTs due to slow variation in the phase of the local plane wave. By tailoring antenna focal plane characteristics, a compact free-space setup that is <inline-formula> <tex-math notation="LaTeX">$6\\times $ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$10\\times $ </tex-math></inline-formula> smaller than the classical setup for handling MUTs that are 1/5th of the size used in classical setup is demonstrated without compromising the measurement accuracy.
