Digital Beamforming Antenna Array to Unknown Interference Countermeasure

An optimal beam forming method is proposed which incorporates all electromagnetic characteristics of the antenna elements, including radiation pattern, mutual coupling and radome effect. The optimal beam forming technique minimizes the total power radiated by the antenna array while the response in a desired direction is maintained. By considering the active element patterns efficient beam forming algorithm is obtained which is able to manage all mutual coupling effects. Simulation results show the performance of the proposed algorithm applied to an antenna array.
