Abstract
In this paper, a printed slot antenna fed by a co-planar waveguide for ultra wide bandwidth (UWB) with dual notch bands has been presented and discussed. The band notches are realized by etching one C-slot resonator inside a plaque shape exciting stub as well as symmetrically adding a pair of open-circuit stubs at the edge of the slot resulting in dual stop band flltering properties for WiMAX, WLAN application. Surface current distributions are used to analyze the efiects of the slot and open circuit stub. The proposed antenna is fabricated and experimental results show that it has an impedance bandwidth of 2.6{14.34GHz for VSWR • 2, except dual frequency stop-bands of 3.3{3.7, 5.04{6.0GHz. From the simulation results, it is observed that the radiation patterns are omnidirectional in the H- plane and dipole like nature in the E-plane. The gain varies from 3.7dB to 5.7dB over the whole UWB region excluding at notch bands.
