Abstract:

The need for compact, high-gain, wideband antennas that can facilitate high-speed and low-latency transmission has increased due to the rapid expansion of fifth-generation (5G) wireless communication. For 5G millimeter-wave applications, this paper details the design and performance analysis of a square microstrip patch antenna operating at a resonant frequency of 18.305 GHz. In order to achieve improved radiation characteristics and impedance matching, the antenna was constructed and examined using a full-wave electromagnetic modeling environment. With a return loss (S11) of -17.27 dB, the recommended antenna demonstrates effective impedance matching at the operating frequency. Additionally, it has an impedance bandwidth of 3.1 GHz, which makes it perfect for broadband 5G communication systems. The anticipated VSWR of 1.31 confirms effective power transmission with minimum reflection losses.Additionally, the antenna’s gain of 6.49 dBi and directivity of 8.41 dBi demonstrate adequate radiation performance for high-frequency wireless applications. The simulation results show that the proposed square microstrip patch antenna offers a well-balanced combination of compact dimensions, broad bandwidth, constant radiation characteristics, and effective performance. The proposed antenna is a feasible choice for next-generation 5G wireless communication systems, including fixed wireless access, high-speed mobile networks, and other millimeter-wave communication applications.
