Abstract: A phased array antenna with a high impedance surface according to an embodiment of the present disclosure is a phased array antenna with a high impedance surface including a plurality of unit elements, and each of the plurality of unit elements includes a substrate, a partial ground plane formed at least partially on the substrate, a planar inverted-L radiator disposed on the partial ground plane, and a via wall integrated in parallel on both edges of the partial ground plane, and a one-dimensional electromagnetic bandgap (EBG) structure is embedded in an edge of the planar radiator side of the partial ground plane.
