An ultra-wideband (UWB) antenna with a narrow frequency notch is presented. The antenna has been fabricated on a FR4 substrate and occupies an area of only 25 × 25 mm. Starting from a Circular planar patch exhibiting a VSWR smaller than 2.5 in the 3.5−10 GHz band, a frequency notch at 5.65 GHz is introduced by two open slots above the coplanar waveguide feeding. The measured return loss shows a...

A planer monopole ultra wideband (UWB) antenna with single and dual band notched characteristics are presented in this article. Proposed antenna consists of simple rectangular shaped patch with sequential notches which is inserted in two lower corners. In order to obtain band notched properties ‘U’ shaped conductor backed plane (CBP) is embedded. Multiple ‘U’ shaped CBP can realize multiple fre...

The presented paper exhibits the design configuration of Microstrip Line (MS)-fed and Co-Planar Waveguide (CPW)-fed symmetrical staircase shaped, planar monopole Ultra Wideband (UWB) antennae with WLAN band rejection characteristic having sized 30x30x1.6mm. The staircase pattern in the radiating patch and the feed line’s Ushaped slot are used to achieve the UWB and notch the 5GHz WLAN band, res...

In this paper, a microstrip-fed hexagonal shape ultra-wideband (UWB) monopole antenna with triple notched bands is presented. The antenna consists of a microstrip feed line, a regular hexagonal shape radiation patch with a complementary split ring resonator (CSRR) and a pair of inverted T-shaped conductor-backed planes embedded in the antenna backside. Notched bands can be easily controlled by ...

In this paper, the analysis of a modified E-shaped patch antenna is presented. The purpose of the modification over the original Eshaped structure is to accommodate the operating frequency band and signal bandwidth requirements of the Ultra Wideband (UWB) wireless system. Simulation results show that the modified E-shaped has fulfilled the frequency band and signal bandwidth requirements of the...

DESIGN AND OPTIMIZATION OF UWB ANTENNA FOR AIR COUPLED GPR APPLICATIONS Report Title This thesis presents a novel antenna structure that satisfies the challenging requirements of an air coupled high speed ground penetrating radar (GPR).

─ 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...
