Radiative properties of Microstrip Patch antenna at dual band and dual feed

Abstract

A new design model is proposed for microstrip patch antenna which works with dual band and dual feed technology, the antenna patch is designed with copper material in rectangular shape. The proposed antenna operates on two frequencies, the first 2.4GHz and the second 5GHz, which is suitable for WLAN applications. This antenna was designed by a 3D simulation program CST Microwave Studio 2019 and from the simulation results we obtained, the VSWR quantity at the first frequency was 1.108281 and at the second frequency its value was 1.199105, and the return loss at the first frequency was -25.8787 dB and at the second frequency -20.863 decibels. As for the directivity, the value at the first frequency was 3.497 decibels, and at the second frequency was 3.315 decibels. These are excellent results and are consistent with the required experimental results
