Reconfigurable UWB printed monopole antenna with band rejection covering IEEE 802.11a/h

Reconfigurable microstrip UWB printed monopole antenna has been designed, analyzed, fabricated and measured with WLAN/Hyperlan2 band rejection characteristic. Band notch is realized by adding a parasitic patch in the back plan then it is cut into two parts which are connected by mean of two RF switches. The ON and OFF state of these switches enables and disables the band notch and hence reconfigurability is introduced. Simulation and experimental results are compared as well as simulated radiation pattern for the two states (ON/OFF) are presented. Also parametric study for optimizing different design parameters is investigated.
