A Planar Dual-Polarized Phased Array With Broad Bandwidth and Quasi-Endfire Radiation for 5G Mobile Handsets

A planar dual-polarized phased array is proposed for 5G cellular communications. The has the properties of dual-polarization, wideband, and quasi-endfire radiation, which printed on one side a single-layer substrate. design contains two eight-element subarrays including horizontally polarized endfire dipole antennas vertically periodic slot antennas, employed PCB ground plane mobile platform. Both provide wide bandwidth to cover 28 38 GHz (promising candidate bands). ?10 dB impedance CPW-fed are 26.5–39.5 27.1–45.5 GHz, respectively. Moreover, ?6-dB bandwidth, these values could be more than 20 (24.4–46.4 antenna) 70 (22.3–95 antenna). fundamental characteristics antenna in terms realized gain, polarization, radiation pattern, beam steering investigated good results obtained. clearance less 4.5 mm sufficient applications.
