摘要：
An improved ultra-widehand (UWB) wide-scan (WC) tightly coupled array ('I'CA) is proposed which can provide an impedance bandwidth of 7:1 and a scanning angle of 75 and 45 for E plane and ft plane, respectively. The proposed antenna array is implemented by employing a resistive frequency selective surface (RFSS) and a wide-angle -impedance -matching (WAIM) layer. The designed non -symmetric "tree-branch" -like element is designed together by using a low profile balun, which is placed Z/16 above the ground plane. The array is verified by CST simulations, and the results show that the optimized array can be used for wide-bandwidth and wide scanning applications.
