The design of several reconfigurable antennas and their uses in the contemporary environment are reviewed in this study survey. The design of these antennas presents additional difficulties. Additionally, the many techniques for rearranging the frequency bands are covered in this work. Examples of both hybrid and single parameter reconfigurations are examined along with their respective performances. The characteristics of the current antenna, including its size, efficiency, and gain, are contrasted. This paper presents the different switches that were installed in the antenna to accomplish the reconfiguration. The advantages and disadvantages of various switches, including mechanical switching, MEMS, pin diodes, and varactor diodes, are also discussed. To activate and deactivate the antenna's construction, the diodes are turned on and off. In a similar vein, mechanical switching mechanisms employ mechanical actuators. Various examples are used to review the mechanisms of polarization reconfiguration between linear and circular, as well as pattern reconfiguration between directional and omnidirectional. Furthermore, a thorough review is conducted on multiple designs of MIMO antennas and reconfigurable filtering antennas.
