Patent ID: 8643548

Claim:
An antenna assembly comprising: an aperture unit; a multilayer printed wiring board having a plurality of sub assemblies bonded to each other with a bonding material providing both mechanical and electrical connection, wherein the multilayer printed wiring board is connected to the aperture unit; a plurality of radio frequency radiating elements formed on the multilayer printed wiring board; and a plurality of chip units mounted on the multilayer printed wiring board, wherein the plurality of radio frequency radiating elements are located on one side of the multilayer printed wiring board and the plurality of chip units are located on an opposite side of the multilayer printed wiring board, each radio frequency radiating element in the plurality of radio frequency radiating elements connected to a chip unit in the plurality of chip units, the radio frequency radiating element bonded to the chip unit with the bonding material such that a first via in the radiating element electrically connects with a second via in the chip unit, the bonding material positioned between the first via and the second via, wherein the plurality of chip units includes circuits configured to control radio frequency signals radiated by the plurality of radio frequency radiating elements to form dual beams with selectable polarization.
