Dual Band Notched Square Monopole Antenna with wide bandwidth for UWB Applications
نویسندگان
چکیده
A compact ultra wideband (UWB) monopole antenna with dual band-notched characteristics is presented. The antenna consists a square radiating patch with L shaped slots on the radiation patchand a U shaped slot as the feedline. By cutting two C-shaped slots in the ground plane, additional resonance is excited and hence much wider impedance bandwidth can produced, especially at the higher band, which results in a wide usable fractional bandwidth of more than 127% (3.1-13.2 GHz). With a pair of L-shaped structure and U slot in microstripfeedline frequency band stop performance is generated. The proposed antenna has a size small of 18x20 mm 2 . The simulated results show that antenna covers5.1/5.8 WLAN and 4 GHz Cband with dual band notched function. Keywords—C band,dual band notched,U slot, ultrawideband (UWB), L slot.

This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

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...

─ In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the squ...
