摘要：

A coupled-fed dual-patch antenna with vias, stubs and a metallic shield is proposed. The proposed design shows all the key features of multi-radiation nulls, low cross-polarisation, wide bandwidth, high and flat gain, while the reported single-patch and multi-patch antennas have part of the features. One prototype operated at 10.3 GHz has been fabricated and measured. The measured results show a 10-dB fractional bandwidth of 12.1%, the gain at the centre frequency is 8.7 dBi, and three radiation nulls appear at 7.6, 8.15 and 12.25 GHz, respectively. The cross-polarisation is less than -25 dB. The gain ripple is 0.36 dB.
