Frequency Reconfigurable Antenna

With the increase in wireless applications, there is a need for compact antennas that adapt their behavior with changing system requirements or environmental conditions. Here adapt implies the antenna should be able to alter operating frequencies, impedance bandwidths, polarizations, radiation patterns. These all features are provided by the “Reconfigurable antenna”. The important feature of reconfigurable antenna is that, they provide the same throughput as a multi-antenna system. A compact frequency reconfigurable antenna is designed with the aid of Ansoft HFSS that provides multiple frequency bands. This is achieved by using electrical switches such as PIN diodes. Depending on state of switches different operating frequencies are obtained. The switches placed on the antenna elements are powered wirelessly by the antenna itself. The design, geometries and simulation results of a frequency reconfigurable antenna are presented in this report. Further advancements are to be done for this structure to achieve polarization and radiation pattern re-configurability.
