Large-space wide band phased array antenna

In this paper, one-dimension large-space phased array antenna for chamber test application is presented. The antenna having large space consists of 18 elements, which can provide ±45° scanning range in azimuth plane and impedance bandwidth of 40% for active VSWR<;1.7 over the whole frequency/scanning range. Details of the proposed antenna design are described and simulated results are presented.
