【 摘 要 】
A low-profile circularly-polarized (CP) antenna with broad axial-ratio (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 à 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°) and exhibits a low-profile property with the height of 0.054λ0, which can be applied in the BeiDou Satellite System (BDS).
