摘要：
A low-profile circularly-polarized (CP) antenna with broad axialratio (AR) beamwidth is presented by loading with artificial magnetic conductor (AMC). The antenna consists of a couple of modified dipoles with four crossed symmetrical fan-shaped arms and a magneto-electric (ME) dipole equipped to broaden AR beamwidth. One AMC consists of 5 x 5 units is integrated to reduce the backward scattering wave and simultaneously ensures a low profile. The measured results of one fabricated type reveal that the AMC-integrated antenna accomplishes a wide 3-dB AR beamwidth (> 135 degrees) and exhibits a low-profile property with the height of 0.054 lambda(0), which can be applied in the BeiDou Satellite System (BDS).
