Low-Profile Dual-Polarized Planar Antenna with Compact Structure for Base Stations

摘要

A low-profile dual-polarized planar antenna with compact structure for 2.4GHz Wireless local area network(WLAN) and 2.5GHz Long term evaluation(LTE2500) base stations is proposed.A combination of a planar radiator and compact Artificial magnetic conductor(AMC) reflector is utilized to achieve a full planar structure without adding extra matching circuit,an extremely low-profile of 0.127 wavelength,as well as a high front to back ratio(F/B) of 25 dB.The antenna is fabricated to test the performance such as S-parameters,radiation patterns and peak gain.Reasonable results show the suitability of the proposed antenna for 2.4GHz WLAN and LTE2500 applications.
