Simulation of High-Gain Microstrip Patch Antennas for 5G Applications

Abstract

This paper presents a single-band Microstrip Patch Antenna (MPA) with L, T, and other suitable slots, specifically designed for high-gain  performance in fifth-generation (5G) mobile communication systems. Incorporating these innovative slots onto a single rectangular  patch antenna yielded substantial improvements in gain and bandwidth, addressing the requirements of 5G applications. The investigation was conducted within the Computer Studio Suite (CST) simulation environment, utilizing simulated structures to identify  optimized slot dimensions. The performance and dimensions of the newly modified patch antennas are systematically assessed and  compared against those of a previously developed single microstrip patch antenna and an array designed for operation at 28 GHz. The  results of the proposed antennas exhibited significant gain and directivity, noticeable bandwidth, Voltage Standing Wave Ratio (VSWR),  and efficiency at the selected resonance frequency. The successful implementation of this proposed design holds the potential to greatly  simplify the integration of 5G applications into handheld devices.
