- Enhancement of Microstrip Patch Antenna (MSPA) with Partial Ground

A novel design of microstrip patch antenna using four split ring resonators placed complement to each other on fr4 epoxy substrate has been proposed in this research article. Additionally, partial ground is utilized for increasing the bandwidth of antenna and to make it compatible at X-band range. The antenna design is designed and simulated using High frequency (HF) simulation software (HFSS) version 13. From the simulation of the designed antenna, two resonant frequencies are observed at 10.888GHz and 12.316GHz having minimum return loss of -18.9089 dB and-35.5072 dB respectively making it suitable for HF applications with impedance bandwidth of 1.869GHz. The third improved parameter is VSWR which is found to be optimum with value 0.294 at frequency 12.316GHz and within the acceptable range from 10.888GHZ to 12.316GHz. The same antenna design has been fabricated and results are verified using Vector Network Analyzer. We have noticed that measured results are better than simulated results with three resonant frequencies and optimum return loss of -42.50dB at 11.025GHz. The radiation pattern of designed antenna is also found to be directional making it suitable for X band applications. - Dielectric Resonator Loaded U-shaped Printed Hybrid Antenna for Multiband Wireless Applications

This paper presents a new type of hybrid antenna geometry which can operate over triple bands. It consists of a U-shaped printed antenna and a cylindrical dielectric resonator antenna (CDRA) along with a ground plane which contains T-shaped slot. The proposed antenna operates over frequency ranges 5.75-6.56 GHz, 9.46 -12.7 GHz and 14.29-16.13 GHz and provides peak gain about 7.3 dBi. Different modes of CDRA like HEM11δ, TM01δ-like, HEM12δ and HEM21δare being excited. The proposed antenna can be used as an electromagnetic sensor for C, X and Ku band applications. - Compact Electromagnetic Bandgap (EBG) Structure with Defected Ground
P. Prakash, M. Abegaonkar, L. Kurra, A. Basu and S. Koul
ABSTRACT In this paper, a compact defected ground mushroom electromagnetic bandgap (DG-MEBG) structure is presented. Compactness is achieved by employing a DG in the conventional MEBG. DG-MEBG exhibits a low pass transmission response with a cut-off frequency of 4.2 GHz and wide stop band up to 17 GHz as against a cut-off frequency of 10.4 GHz observed in a conventional MEBG. Thus the proposed DG-MEBG is 60% compact in comparison with a conventional MEBG structure. The measured results show a very good agreement with the simulated ones. - Gain enhancement of a CPW-Fed monopole antenna using polarization- insensitive AMC structure
P. Prakash, M. Abegaonkar, A. Basu and S. Koul
A polarization-insensitive dual-band artificial magnetic conductor (AMC) structure is designed and experimentally verified. It consists of a planar array of annular ring-slot loaded rectangular patches. Details of the proposed structure and origin of the two bands is discussed. Through simulations and measurements, it is shown that the structure is insensitive to polarization of the incident wave. The tuning of the higher AMC band is demonstrated by varying the capacitance of the annular slot through its width variation. The designed AMC is used as a reflector for a wideband monopole patch antenna. It is shown experimentally at the antenna frequencies in the AMC band that the gain of the antenna improves by almost 10 dB and front-to-back ratio is improved by 15 dB. - A simple harmonic reduction technique in inset-fed microstrip patch antennas
