摘要：
In this letter, a wide-beam (at two main planes) antenna is proposed. To broaden the 3 dB beamwidth of the original antenna, a pair of parasitic patches with metallic vias is creatively arranged on either side of the original radiation patches. Based on the proposed antenna element, two linear phased arrays are fabricated and measured. Measured results reveal that the wide-angle scanning capability of both H-plane and E-plane arrays can be obtained. The scanning beam of the former can cover territories ranging from -90 degrees to 90 degrees, with gain loss within 3 dB (8 GHz-11 GHz). The scanning beam of the latter can cover territories ranging from -70 degrees to 70 degrees, with gain loss of 3-5 dB (8 GHz-10 GHz).
