Abstract: Wireless Systems are subjected to overwhelming advancements with the exponential demands in the field of Communication. This has led to the evolution of Reconfigurable antennas which gained enough significance as they are capable of modifying them.selves to different operating frequencies, patterns or polarizations. Out of these, Frequency Reconfigurable Antennas which can be operated at multi-frequency environment have been found to have a wide range of applications. The reconfiguration can be achieved using various switching mechanisms like, electrical, optical, etc. These are found to support various communication standards, ensure effective utilization of spectrum, reduce system complexity and hence cost. The recent researches on frequency reconfigurable antennas using electrical switches are analyzed in this paper based on their performances and a comparison on various switching techniques is presented.
