Design, Simulation & Analysis of Rectangular & Circular Microstrip Patch Antenna for Wireless Applications

Abstract

While the revolution in antenna engineering leads to the fast-growing communication systems, Microstrip Patch Antennas (MPA) have proven to be the most unconventional discovery in the epoch of miniaturization. This paper incorporates the designing, simulation, and analysis of rectangular & circular microstrip patch antennas. The resonating frequency of the proposed patch antennas is 9 GHz, lying in the X band region and are designed on Rogers RT/duroid 5880 material having dielectric constant 2.2, using Ansys HFSS software. The proposed MPAs were compared on the basis of five performance parameters (Return loss, Bandwidth, VSWR, Gain and HPBW). It was observed that rectangular MPA has a higher value of return loss, VSWR and HPBW than circular MPA. Whereas, circular MPA has greater bandwidth and gain than rectangular MPA. The proposed antennas can be used in radar, wireless and satellite applications.
