A 30 Ghz Slotted Bow-Tie Rectangular Patch Antenna Design For 5g Application

Abstract

In this work, we suggest a new rectangular microstrip patch antenna (RMPA) with a relative permittivity (ɐr) of 4.3 and a thickness (h) of 0.254 mm, and we examine its design and performance at (f).The wavelength is 28 GHz. In order to enhance the antenna radiation performance, particularly the antenna gain and bandwidth, three distinct feeding strategies are explored utilising Computer Simulation Technology (CST) and the High Frequency Structure Simulator (HFSS): microstrip inset line, coaxial probe, and proximity linked line. Although it has a bigger antenna than the other feeding options, the proximity-coupled fed still manages to produce a highly directed pattern and keep radiation performance good, according to the simulated frequency responses. The three feeding methods increase the gain from 5.50 dB to 6.83 dB. Furthermore, for f r = 28 GHz, with the reflection coefficient S11= -10 dB, the antenna bandwidth is enhanced from 0.6 GHz to 3.60 GHz. The suggested architecture is more suited to various 5G application systems than the previously developed RMPA due to its greater bandwidth, higher gain, and dependable size.
