Performance Enhancement of Triangular Patch Antenna by Optimizing the Feed Point Location

Abstract

In this paper, a design and analysis of microstrip fed triangular patch antenna is presented for microwave applications. The performanceof an edge fed antenna design is enhanced by selecting proper dimension and feed point location of matching quarter wave transformer. The designed antenna resonates at 10 GHz with S_11 = -18.28 dB and with maximum gain of 8.73dB and radiation efficiency is 99.24% for the centre location of the feed. The gain, directivity and other parameters of the triangular patch antenna are affected by localizing the feed point with the constant thickness of substrate. The design has been simulatedby the application of HFSS software based on finite elemental method.
