Abstract

A low-profile compact uni-planar slot antenna design of size 26 mm × 26 mm is proposed, assisted with a metallic bottom reflector at a height of λ/6 (λ is the lowest CP frequency). The dual-band dual-polarization is observed at 6.2 GHz and 9.3 GHz, and polarization sense (LHCP and RHCP) is dynamically switched by introducing a pair of RF p-i-n diodes mounted at the confluence of right-slot (RS) and left-slot (LS). The metallic reflector of size 60 mm × 60 mm helps to improve overall impedance matching, enhance antenna gain and asserts uni-directional dual-polarized radiation with good back-lobe suppression. The proposed antenna operates at dual bands (5.46-6.76 GHz) with 21.27% IBW and (8.18-10.48 GHz) with 24.65% IBW for S₁₁ < -10 dB. The antenna gain reaches (7.82-8.75 dBi) for D1-OFF, D2-ON state with (9.2%, 15.63%) axial bandwidths and (6.42-7.0 dBi) for D1-ON, D2-OFF state with (7.53%, 16.04%) axial bandwidths with radiation efficiency ranging (75-87%). A prototype antenna is fabricated and measured, which shows good agreements with simulated performances and can be used for sub-6 GHz in 5G applications and X-band radar systems.
