Abstract

We propose a radiation concept to realize phased arrays with wideband and wide-scanning performance. The array is based on connected-slot elements that radiate in the presence of artificial dielectric superstrates. The array can be implemented with a single multi-layer printed circuit board. Artificial dielectrics are used in place of real dielectrics to minimize the losses due to surface waves and avoid the occurrence of scan blindness over a wide scan range. The achievable bandwidth depends on the number of layers composing the artificial dielectric. A design example is shown that achieves a bandwidth (VSWR<;2.5) of about 5:1 when scanning up to 50° in all azimuth planes. Both single- and dual-polarization designs can be implemented.
