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.
