Design of a Wideband Wide Scanning Phased Antenna Array with FSS Superstrates
|In this paper, a planar wideband antenna array with wide scanning angle in both E - and H -planes is proposed. The dipole antenna is used as an essential element of the array. To enlarge the scanning angle of the array, two layers of frequency selective surface (FSS) superstrates are loaded on the top of the antenna elements. A conducting-patch with shorting pins is loaded under the unit patch to enlarge the bandwidth of the array. Both simulated and measured results have con(cid:12)rmed that the proposed antenna array can scan up to 85 ◦ and 70 ◦ in the E - and H -planes from 8 GHz to 11 GHz, respectively.
