Performance Analysis and Comparison of 5G mm-Wave Microstrip Patch Antenna with Array

Abstract

A microstrip patch antenna that can operate in the 5G mm wave band with a return loss of - 67dB, gain of 7.6 dBi, and coverage of the resonating frequency of 28 GHz is demonstrated in this study. In CST Studio Suite, a 2×2 and a 4×4 array antenna have been created with the same form factor as the patch. This paper also compares the performance of a microstrip patch antenna to an identical array antenna. All of the simulated designs used the substrate Rogers RT 5880, which has a dielectric constant of 2.2. This is extremely useful in contemporary devices due to its small antenna design. Additionally, the gain of the proposed microstrip antenna is 7.6 dBi as opposed to the 13.07 and 15.5 dBi gains of the array antennas simulated results. The antenna has two circular parasitic elements and two slots in the patch, which have a great impact on how well it performs
