Abstract
An antenna array feed network includes two or more antenna elements, a 180° hybrid coupler, one or more combiners, two or more transceiver systems including a secondary transceiver system with a transceiver, a diplexer, and amplifier with each remaining transceiver system including a transceiver, a diplexer, a directional coupler, a RF switch, a preamplifier, a network circulator, a programmable attenuator, and an amplifier. The two or more antenna elements form an antenna array. The 180° hybrid coupler provides amplitude controlled null steering and two separate RF signals for an individual port of the antenna array. The programmable attenuator provides automated null steering algorithms for the antenna array feed network. The analog phase shifter equalizes magnitudes of a phase of the two more antenna elements. The one or more combiners feed two or more transceiver systems into the 180° hybrid coupler or the antenna elements into the 180° hybrid coupler.
