Abstract :
This paper presents a new design of printed dual band-notched monopole antenna for ultra-wideband(UWB) applications. Printed on the dielectric substrate, the antenna consists of a disc-like radiator and is fed by a microstrip line. By the use of C-shaped slot and U-shaped slot, the dual band-rejected characteristics are obtained successfully. The effects of variation on slots are both investigated in detail in this paper. Simulation and measurement results show that the antenna impedance bandwidth covers the frequency range of 3.1-10.6GHz, which meet the requirements of UWB applications well. It is shown that the proposed antenna has almost omni-directional radiation pattern.
