摘要：
In this paper, a low-profile dual-polarized MIMO antenna with an artificial magnetic conductor (AMC) for WLAN applications is proposed. The antenna consists of two Barron structured feeds combined with each other in ±45° polarization. The significant low-profile (0.0980) advantage of this antenna is achieved by loading an AMC reflector on the bottom of the antenna. The AMC reflector is composed of a patch of 4 × 4 units, which enables the low profile and high gain of the antenna. The antenna is simulated, processed, and measured physically, and the measured results show that the proposed dual-polarized antenna has a bandwidth of 21% (2.35-2.89 GHz), a peak gain of 7.34 dBi, and a peak efficiency of 71.5%, which can be used for applications such as WLAN base station antennas. © 2021 Xinghui Jin et al.
