Hexagonal shaped microstrip patch antenna for satellite and military applications

Abstract

In this work, investigation of the effect of different slots in a hexagonal shaped microstrip patch antenna is presented. The proposed antenna is designed on FR4-epoxy substrate and the performance is obtained by using CST Microwave Studio. The antenna has been analyzed for various dimensions of slots and the optimum design has been chosen. By increasing the number of slots, the gain, bandwidth and return loss of the structure has been improved. The simulated antenna structures also show dual band characteristics. The antenna offers application in WiFi IEEE802.11n (2.4 to 5 GHz) and UWB range especially for X-band uplink satellite system (7.9–8.4GHz). As the designed structures resonate in C-band (4-8 GHz), it offers applications in Fixed Satellite Services (FSS) and military also.
