A MIMO Dual-Polarized Antenna Array for Small Cell Application

摘要

This paper presents a MIMO dual-polarized antenna array with high antenna gain performance for small cell application. The proposed antenna is a 4×4 antenna array that formed by 16 patch elements, two antenna ports, two feeding network circuits and a PCB with ground plane. This array antenna can provide wide operating band covering the 4800-5900 MHz met 5G (sub 6GHz) and ISM 5 GHz bandwidth requirement, and has two high directivity radiation patterns at V/H polarization plane individually and has two antenna ports to support 2×2 MIMO system application. This antenna has a low profile of 2.8 mm, and the whole size is 198 × 198 × 2.8 mm³, that can easily mount on indoor wall or ceiling. Details of design considerations of proposed antenna and experimental results are presented and discussed.
