Design and Implementation of High-Gain Wide-Bandwidth Patch Antenna Array  5G Base Stations

This article introduces an analysis and design of an array of elements consisting of four antenna elements connected by a power divider. This proposed antenna possesses better performance for 5G base station mmWave applications. The 1 x 4 T junction power divider feeding technique achieved the design of these arrays. This power divider provided an easy model, low spurious radiation, and the best bandwidth. This work presents an antenna array simulated with the HFSS at a working frequency of 28 GHz.The substrate material used is Roger4003, with a thickness of 0.4 mm, permittivity of 3.5, and a loss tangent of 0.0027. The results of simulations derived from this research work are as follows: VSWR 1, reflection coefficient S11 -34 dB, gain 11 dB, bandwidth 2.56 GHz, directivity 11.1 dB, efficiency 96%. As discussed in the last part of the article, this proposed 5G base station array has realized enhanced performance compared to other antenna array designs. Consequently, it is positioned to arise as a significant contender for 5G applications.
