Polarization Reconfigurable Antenna for Mid-Band 5G applications with a new reconfigurable technique

Alaa Imran Imran AL-Muttairi,


In this paper, a novel low cost, single-feed and polarization reconfigurable antenna is designed for mid-band 5G applications. An innovative technique is used in this approach which combines among three techniques namely: polygon U-slot, switchable vertical or horizontal slots, and shorting posts. The proposed technique enables high-performance circular polarization reconfigurable antenna design with adaptive axial ratio metrics. The designed antenna built on Roger RT 5880 substrate with a maximum size of (31*31*3.15) .Two real diodes are integrated across the slot to change polarization sense between right hand or left hand circular polarization. CST commercial software is used to simulate the antenna. From simulation results, the antenna has impedance bandwidth starting from 3.4995GHz to 3.73GHz with overlapped axial ratio bandwidth of 2.1% for both operation senses. Furthermore, the antenna has good gain, efficiency and it has one resonant frequency at 3.6GHz.
