A Wideband Microstrip Patch Antenna with Slotted Ground Plane for 5G Application

Abstract

A wideband microstrip patch antenna (MPA) has been presented for fifth generation (5G) wireless application. The antenna is etched on Rogers RT 5880 (lossy) material (2.2, 0.0009) having compact size of $20\times 20\times 0.79\mathrm{mm}^{3}$. It shows gain of 5.22 dB, directivity of 7.48 dBi and VSWR of 1.036 at resonant frequency 27.47 GHz. Some slots on metallic ground plane of the MPA are made to enhance the intended performance parameters including larger bandwidth and better impedance matching of the antenna. The antenna presents very good return loss (−5.03dB at resonant frequency 27.47 GHz) over a wideband of mm-wave operating frequency ranging from 26.154 GHz to 31 GHz. Due to the scope of obtaining large bandwidth in mm-wave, it is possible to gain a huge amount of data rate at lower latency in 5G technology and the antenna provides a large bandwidth of 4.846 GHz for mm-wave 5G application.
