A Planar Wideband Wide-Scan Phased Array: Connected Array Loaded with Artificial Dielectric Layers

We present a novel concept for wideband, wide-scan phased array applications. The array is composed by connected-slot elements loaded with artificial dielectric superstrates. The proposed solution consists of a single multi-layer planar printed circuit board (PCB) and does not require the typically employed vertical arrangement of multiple PCBs....
