Abstract: An antenna assembly configured to operate in a millimeter wave frequency of 30 GHz to 300 GHz, the antenna assembly being formed from a multi-layer printed circuit board having a plurality of eight square radiating rings positioned at generally equidistant locations within and surrounded by a rectangular grounded external ring which is positioned at the perimeter of the assembly. The antenna assembly also includes a plurality of feed network layers with a radio frequency chip and a baseband chip mounted onto the top of the plurality of feed network layers for controlling the operation of the eight square radiating rings.

Abstract: A broadband phased array antenna system is set forth comprising a support member; an antenna array mounted to the support member, the antenna array having a plurality of uniformly excited hybrid radiating elements arranged in a symmetric array on a substrate; a baseband controller mounted to the support member; a radio controller mounted to the support member for modulating and demodulating signals between the baseband controller and antenna array; and a communications interface for removably connecting and disconnecting the antenna system. In one aspect, the antenna array comprises a substrate; a plurality of uniformly excited hybrid radiating elements arranged in a symmetric array on the substrate; a hybrid feeding network for transmitting RF-signals to the hybrid radiating elements; and artificial materials surrounding opposite sides of the symmetric array for suppressing edge scattered fields and increasing gain of the antenna system.
