The method of auxiliary sources applied to the analysis of adaptive transverse resonant antennas

Abstract

The beam-steering capability of compact antennas presenting transverse resonances could be employed in wireless applications. Adaptive beam-steering arrays can improve communication reliability and energy efficiency. The 2-D method of auxiliary sources is employed to study the performance of a compact size transverse resonant antenna composed of wire radiators embedded in a dielectric substrate and backed by a conductive surface. In this particular case, the antenna is capable of scanning and changing the width of the main lobe of its pattern, as well as reduce the back radiated energy. Attention is paid to energy absorption by the user's body, as well as to EMC issues with body-worn electronic devices.
