Design of a Corporate fed 1×2 Microstrip Array Antenna for X Band Applications

Abstract

This article presents a simple 1×2 Rectangular microstrip array antenna fed by corporate feed network. The array is designed to operate in X Band using FR4 as Substrate with permittivity, Ɛ r =4.4 and height, h=1.66mm. The proposed array antenna has dual band characteristics. The parameters of the antenna are selected to achieve the compact dimension. The designed array antenna is simulated using HFSS v12 simulator and simulation results are shown in terms of return loss, VSWR, radiation pattern and gain are presented. The results show that the antenna has dual band characteristics with the overall impedance bandwidth (VSWR≤2) of about 20.52%. The proposed antenna array is suitable for applications such as Satellite communication, Radar and other Wireless systems.
