Abstract

Background: Several rectangular Microstrip Patch Antennas (MPAs) with different substrates are designed to achieve high gain and high data rate for the 5G cellular band. One of these which uses a Polymethacrylate / Rohacell 51 as a substrate material provides a high gain of 10.054 dB and a moderate bandwidth of 80 MHz (2.28 % of f0).

Objectives: This MPA can be preferred for 5G cellular base station antenna in 3.3 GHz - 3.7 GHz with center frequency (f0) 3.5 GHz. Considering this high gain rectangular MPA, several compact MPAs are designed with the help of simple pin shorting and chip impedance shorting techniques.

Methods: Simple pin shorting compact design provides a patch area reduction of 97.09 %, a gain of 3.77 dB, and a bandwidth of 60 MHz. Chip impedance shorting is preferred to overcome the effect of narrowband in simple shorting and rectangular MPA.

Results: One of these which provides an improved bandwidth of 170 MHz (4.86 % of f0) and significant gain of 1.51 dB with 93.575 % patch area reduction can be preferred for mobile devices for 5G cellular in 3.3 GHz - 3.7 GHz.

Keywords: Compact patch antenna, 5G cellular band, chip shorting, UHF band, patch, area, MPA.
