Abstract:
A novel tri-band pattern reconfigurable planar antenna is proposed. Tri-band is achieved by inserting a bandstop filter at the feed line of a wideband monopole antenna with complementary split ring resonator (CSRR) on a circular patch. Two parasitic arc-shaped stubs are in the back side of the radiator that works as a reflector. The antenna radiation pattern is switched from omnidirectional to one of two different directional modes by activating one of the stubs. Three different radiation modes are controlled by four ideal switches. Radiation pattern reconfigurability makes it suitable for the use of flexible cognitive radio front-end system. The proposed antenna is suitable for WLAN 2.4/5.2/5.8 GHz and WiMAX 3.5/5.5 GHz applications. Good agreement between simulated and measured results validates its possible application.
