Design of Frequency Reconfigurable Micro-Strip Patch Antenna for Wireless Applications
In this paper, the authors present innovative design of a compact reconfigurable microstrip patch antenna system using different rectangular rings. Switching between different frequency bands are achieved using six RF-MEMS switches. The antenna is capable to reconfigure up to three different frequency bands. Empirical relations relating to the design for rectangular rings for desired frequency band are included in the paper. The proposed microstrip patch antenna structure is fed by microstrip line feed. The antenna is designed to operate at 2.4GHz, 3.5GHz and 4.8GHz. The proposed antenna provides triple bands in which the bandwidth of 367MHz for 2.45 GHz, 799MHz for 3.5GHz and a bandwidth of 3.47GHz for 4.8GHz has been obtained.
