Re-configurable Antennas

Reconfigurability in an antenna system is a desired characteristic that has been the focus of much research in recent years. Reconfigurable antennas, with the ability to radiate more than one pattern, at different frequencies, and with various polarizations offer several degrees of freedom to antenna designers. In this paper, several reconfigurable antenna architectures with and without MEMS switches are presented and discussed. The different issues encountered during the design of the overall antenna design are described herein.
