The design and implementation of electrically small reconfigurable patch antennas

In modern times, a large part of communication equipment is getting smaller with a great need for power efficient and electrically small wireless devices. Wireless devices are not limited to one standard and can operate at multiple frequencies. The key characteristic of future generation wireless communication systems is the ability of antenna reconfiguration. Reconfigurable antennas are considered as a promising paradigm that can generate many modes using a single antenna structure. In this paper, the design and implementation of electrically small reconfigurable patch antennas is presented. Different designs are developed and simulated. The designed antennas are fabricated and tested. The performance of the fabricated antennas is evaluated and analyzed.
