摘要
A novel wideband antenna array with coplanar waveguide series feed is proposed in this letter. By etching a symmetrical circular slot (SCS) structure on the bottom metallic layer, the impedance characteristic of the antenna array is greatly improved. Meanwhile, the gain of the antenna array at the lower band is improved by inserting another SCS in the center of the two array elements. The measured results show that the impedance bandwidth of the proposed antenna array is from 2.04 to 3.74 GHz (the relative bandwidth is 58.8%). Moreover, the maximum gain reaches 6.9 dBi.
