A novel multiband frequency reconfigurable antenna for WiMax and Wi-Fi application

In this paper we have presented a novel design of miniaturized microstrip antenna used for wireless applications. The antenna is based on reconfigurability property, consisting of one switch which is used to change the surface current distribution and hence the frequency of operation. Antenna in ON state have dual band at 3.5GHz and 5.8GHz, while antenna in OFF state have a single band at 5.8 GHz. Both simulated and measured result are in close agreement. It is switchable either at 3.5 or 5.8 or both the bands depending on the different switch conditions.
