Design and Simulation of Millimeter-Wave Patch Antenna Array for 5G Mobile Devices and Small Cells Using HFSS
Abstract
The rapid evolution of fifth generation (5G) network has become important in addressing the increasing demand for faster data usage, lower latency, and increased system capacity. Fully operating in the millimeter-wave frequency band, 5G networks need versatile, high-performance antennas which are capable of overcoming propagation losses and ensuring reliable signal transmission. A 28 GHz microstrip patch antenna design, and 2, 3, 4, and 5-element arrays are presented in this paper. FR-4 substrate material with a thickness of 0.8 was designed for the antenna, and dielectric constant (εr) of 4.4 to operate at 28 GHz and analyzed using HFSS (High-Frequency Structure Simulator). At 28.38 GHz, the simulation results show a return loss, bandwidth, VSWR, gain, and directivity of -24.21 dB, 2.61 GHz, 1.06, 5.43 dB, and 6.37 dB, respectively. At 28.38 GHz with a gain of 5.43 dB for each element, the gains for 2, 3, 4, and 5-element microstrip antenna arrays are 38.67 dB, 41.79 dB, 44.04 dB, and 46.10 dB, respectively. Although the present work is limited to numerical simulation but the proposed antenna has a high potential for use for 5G devices and small cells.
