The method of auxiliary sources applied to the 3-D analysis of the compact resonant antennas

Compact adaptive volume-resonant antennas with beam-steering capability could be employed in wireless applications. The described antenna can radiate the energy in desired direction within certain range of angles by changing the amplitudes and phases of feeding currents of the dipoles printed on the dielectric substrate with a conductive back surface. The improved efficiency entails a lower RF exposure of the user for equal power emitted compared to conventional linear antennas. The 3-D method of auxiliary sources (MAS) is employed to study the performance of the presented antenna.
