Abstract

This paper presents a circular polarization reconfigurable antenna for 5G applications, which is compact in size and has good axial ratio and frequency response. The proposed microstrip antenna is designed on a FR-4 substrate with a relative dielectric constant of 4.3 and has a maximum size of 30 × 30 mm2 with 50 Ω coaxial probe feeding. This design has two PIN diode switches controlling reconfiguration between right hand circular polarization (RHCP) and left hand circular polarization (LHCP). To achieve reconfigurability, a C-slot rectangular patch antenna with truncated corner techniques is employed by cutting off two corners on the radiating patch. The proposed antenna has been simulated using CST microwave studio software: it has 3.35–3.77 GHz and 3.4–3.72 GHz bands for both states of reconfiguration, and each is suitable for 5G applications with a good axial ratio of less than 1.8 dB and good gain of 4.8 dB for both modes of operation.

Many recent books and articles have discussed the use of reconfigurable antennas for “green” flexible RF in 5G applications [1-3]
Other researchers have presented designs for 5G applications – for example in [12], an antenna is designed with circular polarization reconfigurability between left hand circular polarization (LHCP) and right hand circular polarization (RHCP), applicable in mobile systems
