An antenna assembly includes: a support member having opposing first and second sides; an input electrical contact and an output electrical contact; a first array of transmission patch elements supported on the first side and connected to the input electrical contact, the first array configured to receive an input signal via the input electrical contact and generate outbound radiation according to the input signal; a second array of reception patch elements supported on the first side and connected to the output electrical contact, the second array configured to receive inbound radiation and generate an output signal at the output electrical contact according to the outbound radiation; the first array and the second array having a common phase center.

Antenna arrays with common phase centers

A wireless communication assembly includes: a primary support member defining a primary mounting surface with first and second electrical contacts; an antenna, adjacent to primary mounting surface perimeter, and a baseband controller, on the primary support member; primary signal paths between the baseband controller and the first contacts; primary feed lines between the second contacts and the antenna; a secondary support member carrying a radio controller and defining a secondary mounting surface with third electrical contacts and ports adjacent to a perimeter of the secondary mounting surface; secondary signal paths between the third contacts and the radio controller; secondary feed lines between the radio controller and the ports; the secondary mounting surface configured to engage with the primary mounting surface to connect the first contacts with the third contacts, and the second contacts with the ports.

Wireless communications assembly with integrated active phased-array antenna

An antenna assembly includes a support member having opposing first and second surfaces, and a set of electrical contacts; an antenna carried on the first surface of the support member and electrically connected to the set of electrical contacts; a conductive inner ring element carried on the first surface and surrounding the antenna; and a dielectric outer ring element mounted on the first surface and surrounding the conductive inner ring.

Antenna and wireless communications assembly

A wireless communications assembly includes: a primary board including: (i) an upper surface bearing a radio controller, and defining a set of control contacts for connection to respective ports of the radio controller; (ii) a lower surface opposite the upper surface, the lower surface defining a plurality of antenna contacts; (iii) a plurality of conduits extending through the primary board from the antenna contacts to the control contacts; and (iv) an antenna ground plane; a superstrate board including: (i) an inner surface facing the lower surface of the primary board; (ii) an outer surface opposite the inner surface; (iii) a phased array of antenna elements disposed on the inner surface; and a surface-mount package between the lower surface and the inner surface for connecting a subset of the antenna contacts directly to the antenna elements and to provide a substrate between the antenna elements and the antenna ground layer.
