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 ...

An ultra-wideband (UWB) antenna with a novel multilayer frequency selective surface (FSS) reflector is presented. A significant enhancement in the gain has been achieved in a low profile design while maintaining the excellent impedance bandwidth of the UWB antenna. The average peak gain of the antenna has been increased from 4 dBi to 9.3 dBi as a consequence of the use of the FSS reflector. Mor...

Ultra wideband (UWB) technology based on the use of very narrow pulses on the order of nanoseconds, covering a very wide bandwidth in the frequency domain, is one of the most promising solutions for future communication systems due to its high-speed data rate and excellent immunity to multipath interference. In this context, the antenna is one of the important components which determine the per...

─ A simple and compact microstrip-fed ultra wideband (UWB) slot antenna with dual band-notch characteristic for UWB applications has been presented. In order to increase the impedance bandwidth of the square slot antenna, we insert a T-shaped slot in the ground plane that with this structure UWB frequency range can be achieved. Additionally, by using a pair of Lshaped slits at the square radiat...

An Ultra Wideband (UWB) antenna is proposed in this paper which covers the whole FCC UWB band from 3.1 to 10.6 GHz while filtering out the WLAN frequencies around 5.8 GHz. The antenna is a planar wineglass shaped slot antenna fed with a coplanar waveguide. The filtering property has been achieved by etching a semicircular parasitic slit on the excitation element of the antenna. The location of ...

This paper presents the design with optimum geometry of a novel UWB rectangular patch antenna. A simple narrowband patch antenna is designed before proceeding to the geometry of UWB antenna.
