Abstract :
A planar elliptic ultra wideband (UWB) antenna with reconfigurable band-stop performances was successfully designed and manufactured for multi-standard wireless communication systems. The proposed antenna consists of a very high selective band-rejected UWB micro-strip fed monopole operating from 0.65 to over 6 GHz. Frequency agility was produced by loading a varactor diode on the open loop resonator printed on the front side of the substrate close to the micro-strip feeding line. The frequency reconfigurable monopole achieves extremely sharp and narrow band rejection of the WiMAX (3.5 GHz) band when the varactor diode is disconnected. A prototype was realized, the measured reached tuning range of the fabricated reconfigurable antenna is from 3.869 to 4.344GHz. Measured results are presented and discussed.
