- Abstract
- Dual-band dual-polarized proximity fed patch antenna for 28 GHz/39 GHz 5G millimeter-wave communications is proposed. A proximity fed square ring and a square patch were stacked and optimized for dual resonances at 28 GHz and 39 GHz. Two microstrip lines placed orthogonally to each other were used to generate the dual polarization. The simulated -10-dB S11 bandwidth was 400MHz (27.88-28.28 GHz) in 28 GHz band and 720 MHz (38.56-39.28 GHz) in 39 GHz band. The proposed antenna showed good radiation performances with low cross polarization level in both frequency bands. The sufficient isolation between the input ports 1 and 2 makes the consistent radiation performances with varying polarization mode in both 28 GHz and 39 GHz bands.
