MULTILAYER MICRO STRIP PATCH ANTENNA FOR BROADBAND APPLICATIONS

Abstract

In this study, a multilayer microstrip patch antenna's design and modelling utilising the HFSS are presented. The proposed antenna is small and made for broadband applications. A substrate, a patch layer, and a ground plane make up the antenna. The performance of the antenna is evaluated using a Vector Network Analyzer (VNA), and the acceptable range of performance traits like Directivity, return loss, and VSWR is specified. The simulation outcomes demonstrate that the proposed antenna has a broad bandwidth between 3 and 5.5 GHz, which spans both the WLAN and WiMAX frequency bands. The antenna offers a low VSWR of less than 1.5 over the full operational bandwidth, good directivity of 8.5 dBi, and low return loss of -20 dB.The proposed antenna can be used for many different applications involving wireless communication due to its small size, broad bandwidth, and acceptable performance criteria.
