Abstract :
In this paper, applying DGS to a linear six-element microstrip scanning array antenna, the blindness angle is removed. The method of moments is utilized in analyzing the proposed structure. The technique uses the band-stop characteristics of microstrip line filters to block the surface waves and reduce the coupling between elements that cause the blindness angle.
