Performance Analysis of Hybrid Microstrip Patch Antenna at Ka-Band

Abstract: In wireless communication system antenna plays vital role. Therefore, the need for antenna used in any communication system should be low weight, low profile, low cost, smaller in dimension and conformity. A microstrip patch antenna fulfills all these requirements. This paper presents design of hybrid microstrip patch antenna array operating at Ka-band. The hybrid microstrip patch antenna consists of a triangular patch mounted on a rectangular patch. The signals from the antennas are combined or processed in order to achieve improved performance over that of a single antenna. The antenna is tuned at resonance frequency of 28 GHz and its bandwidth is from 26.5 GHz to 40GHz. This technique is used to analyze the performance of �HYBRID PATCH ANTENNA ARRAY� using different feeding techniques like microstrip and coaxial feeding techniques by using HFSS software.
