Abstract :
A novel, phase-only adaptive nulling algorithm has been developed as an ´applique´ for a multimode circular antenna. It provides the capability to suppress undesired jamming signals by spatial filtering. The algorithm minimizes the antenna´s output power while maintaining the direction of its main beam. It has been verified through computer simulation and experimentation.<>
