摘要：
A dual-wideband dual-polarized antenna array is proposed for millimeter-wave systems. Dual bands and dual polarizations are supported by two layers of gridded patches and wideband feeding structures. A 2x2 array is composed for beam scanning. High isolations and stable radiations are achieved by several groups of fences in the array. A prototype is fabricated and measured to validate the design. The bandwidth is 23.65-31.05 GHz and 41.85-46.00 GHz for both polarizations with isolations better than 19.8 dB. Meanwhile, the average gains achieve 12.1 dBi for the lower band and 11.2 dBi for the higher band, providing a scanning range from -33 degrees to 31 degrees and -22 degrees to 21 degrees.
