Design and Analysis of Frequency Reconfigurable Equilateral Triangular Microstrip Patch Antenna

Abstract

This paper describes the investigation of a frequency reconfigurable equilateral triangular microstrip patch antenna (ETMPA). An equilateral triangular microstrip patch is designed using C-shape slots based DGS ground structure to enhance the bandwidth requirements. Here the frequency reconfigurable triangular microstrip patch antenna is proposed by modifying the C-shape slots width by using two MPP4203 RF PIN diodes. The frequency reconfigurability of DGS ground based ETPA is analyzed at 1.93 GHz and 3.78 GHz for L and S band based satellite and 4G mobile communication (E-UTRA 43 band), respectively. The Ansoft HFSS simulation based radiation patterns shows a gain of 2 dB at 1.93 GHz and 2.4 dB at 3.78 GHz resonant frequencies for proposed triangular microstrip patch design.
