Design of Dual-Band Ā-Shaped Patch Antenna for 5G at 27/34 GHz using FR4/RT duroid Material

The present paper presents an innovative structure for an A rectangular shape Microstrip Patchy Antennas (RMPA) that is energised by microstrip lines and fine-tuned for deployment across the Ku/Ka and 5G technological frequencies spectra. The slotted configuration of the antenna endows it with a broader bandwidth, thereby rendering it versatile for deployment across a gamut of applications such as 5G communication, wireless and serviced communications via satellite, radiolocation, radionavigation, and research in space. Specifically, the antenna is optimised for the frequency range of 28-34 GHz. The antenna under consideration has been fashioned utilising a substrate material composed of FR4 and Rogers RT6202, possessing a permittivity with a relative value of 4.4 and 2.94, respectively. The substrate has a thickness that is 1.6 mm. The simulation of the slotted RMPA has been conducted through the utilisation of the advanced microwave studio CST 2022 software. The outcomes of this simulation have been meticulously scrutinised and deliberated upon. The designed antenna operates between 28 and 34 GHz with a return loss of below -10 dB and a VSWR of less than 2. The implications of this observation indicate that the antenna exhibits a high degree of compatibility with 5G connectivity, communication through satellites, and other programmes in the Ku/Ka bands of frequencies. The antenna's condensed configuration renders it a compelling option for assimilation into diverse communication frameworks.
