A Racket-Shaped Slot UWB Antenna Coupled with Parasitic Strips for Band-Notched Application

A racket-shaped slot ultra-wideband (UWB) antenna coupled with parasitic strips for band-notched application is proposed in this paper. By attaching a pair of parasitic rectangular strips on the bottom of the substrate, a band-notched characteristic is well realized. Adjusting the length, width of the two strips and the distance between them, a band-rejected fllter characteristic at the WLAN operation in 5.15{5.825GHz frequency band can be obtained. The fabricated antenna has a small size of 20£37:5mm 2 . Good agreement is achieved between the simulated and measured results, both of which show an ultra-wide impedance bandwidth from 3.1 to 10.6GHz for VSWR less than 2 except the bandwidths of 5.15{5.825GHz for WLAN.
