A Triple Band-Notched UWB Antenna Using Folded Resonators

A triple band-notched ultra-wideband (UWB) monopole antenna etching novel folded resonator on the radiating patch, ground and between the feeding-line, is presented in this paper. The tri-rejection bands are 5.16.1 GHz, 7.6-8.8 GHz and 10.1-10.8 GHz which have covered bands of WLAN and ITU 8 GHz. To analyze the principle of proposed antenna, the simulation of parametric study and distribution of surface current are carried out. The size of antenna is 32mm x 19 mm x 1mm. And the test results are in good agreement with the simulation, which indicate that the antenna is promising for UWB system.
