Multi-notched Printed Monopole Antenna for Uwb Application
نویسندگان
چکیده
A compact printed ultra wideband (UWB) monopole antenna with multi-notched characteristics is presented. By inserting multiple E-shaped slot in micro strip feed line and ground plane, additional resonances are excited. The multi notch has been created by embedding a pair of – L shaped arm in the radiating patch and a modified E-slot defected ground structure in the feeding line. The designed antenna has a small size of 20 X 18 mm 2 and operates over the frequency band between 4.5 and 11.8 GHz for VSWR < 2. The VSWR and radiation patterns of the antenna are presented, which prove that the designed antenna is a good candidate for various UWB applications. Keyboards: Multi notched bands, E-slot, planar monopole antenna, ultra wideband (UWB) antenna.

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...
