Abstract
Fifth generation (5G) mobile networks utilize millimeter-waves (mm-waves) to achieve higher data rates. This paper presents a dual-polarized antenna array that operates at 28GHz (27.5-29.5GHz) and 38GHz (37-39GHz) bands and is usable in mobile handsets. The array is based on slot antennas with separate feeds for each polarization and band. The multi-feed structure allows us to improve isolation between bands. The dual-polarized array has a peak realized gain of 10-13dBi and it is capable of beam-steering for up to ± 35° or ± 50° at 28GHz and 38GHz bands, respectively. The performance of the array in the presence of a smartphone chassis is also studied.
