Abstract: 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.

Abstract: A phased-array antenna assembly includes an antenna board stack, a radome configured to cover the antenna board stack, and a casing configured to support the antenna board stack. The antenna board stack includes a central core, a bottom antenna unit defining a bottom thickness between a bottom surface of the central core and a bottom end of the antenna board stack, and a top antenna unit defining a top thickness between a top surface of the central core and the top end of the antenna board stack that is substantially equal to the bottom thickness. The bottom antenna unit includes two spaced apart bottom metal layers each associated with a different distance from the axis of symmetry. The top antenna unit includes two spaced apart top metal layers each associated with a corresponding one of the distances from the axis of symmetry associated with the bottom metal layers.
