Performance Optimization of Microstrip Patch Antenna Using Frequency Selective Surfaces for 60 GHz

This paper introduces a design of a single rectangular Microstrip Patch Antenna (MPA) with inset feed at frequency of 60 GHz using a Frequency Selective Surface (FSS). After implanting the FSS in the single MPA, it is found that some parameters have been improved. The selected geometry was the Square Loop (SL) element in FSS which has the best performance over other simple shapes. This paper aims to introduce an improvement of the parameter of a MPA, particularly, the gain, return loss, and bandwidth. These improvements has been investigated using Computer Simulation Technology (CST) Microwave Studio (MWS) simulator. The design is performed for 60 GHz applications. The 60 GHz band suffers from severe attenuation due to propagation. The oxygen absorption and the free-space path loss happen at 60 GHz are presumed in this study. These combined factors result in a poor link budget.
