Abstract
An active antenna system developed to beam steer at multiple frequency bands provides improved performance for fixed and mobile communication systems. Methods of altering the current mode on a single radiator are described wherein the radiation pattern of the antenna is varied as the antenna modes are altered. Techniques to restrict or expand the frequency bandwidth of the beam steering technique are described to provide the capability to beam steer at receive frequencies or transmit frequencies only, and techniques are described where beam steering can occur at both transmit and receive frequency bands from a single active antenna system.
