Abstract
This paper present a design of a Frequency Selective Surface (FSS) to improve gain and efficiency of a microstrip patch antenna operating in X-band at 10 GHz. The band-stop frequency selective surface (FSS) designed at the operating frequency of the antenna is used. FSS structure is configured as a superstrate for the microstrip patch antenna. The main goal of this paper is design a compact microstrip antenna module (microstrip patch and FSS structure). Simulation results using CST studio showed that high gain (54 % increment) and efficiency is increased to 97% have been achieved by the proposed antenna module (MS and FSS). The equivalent circuit of proposed FSS unit cell in ADS software has been evaluated and compared to simulation results (CST studio) to improve characteristics of the antenna. The proposed antenna module is extremely compact high gain and it can be used for X-band applications.
