Abstract :
In this paper, a novel frequency reconfigurable monopole antenna with five switchable states including an ultrawideband (UWB) state, three single band states and a dualband state is presented. The frequency reconfigurable capability of the antenna is achieved by using a switchable slotted structure on the ground plane. The antenna which supports most applicable frequency bands above 2 GHz can be used in multi-radio wireless systems. Reflection coefficient and radiation pattern measurements were performed for the fabricated antenna. Good agreement between simulated and measured results was obtained.
