A Millimeter-Wave Planar Dual-Band Array Antenna Having Individually LHCP and RHCP Radiation Characteristics
This article demonstrates a planar dual-band array antenna for millimeter-wave applications, which has a left-hand circular polarization and a fleshlight automatique right-hand circular polarization for two operating bands, respectively.By using aperture-fed stacked-curls, the proposed antenna can attain broad axial ratio (AR) bandwidths in both K-
