摘要：
A phased-array antenna includes an antenna layer of a stacked printed circuit board, a ground plane layer of the stacked printed circuit board spaced apart from the antenna layer, and a first dielectric layer of the stacked printed circuit board disposed between and in opposed contact with the antenna layer and the ground plane layer. The antenna layer includes an associated metal patch pattern defined by a series of slots. The stacked printed circuit board defines a thickness extending between a top end of the stacked printed circuit board and a bottom end of the stacked printed circuit board. The phased-array antenna includes a series of ground vias extending between the top and bottom ends of the stacked printed circuit board. The ground vias are configured to suppress surface waves propagating across the stacked printed circuit board.
