“…As the federal communication commission (FCC) authorized the unlicensed use of frequency band from 3.1 GHz to 10.6 GHz for UWB devices for commercial applications, a great deal of research on UWB technology has come up [7]. UWB antennas as a key component of UWB communication system, have attracted more and more attention in the field of research now a days [8][9][10][11][12][13][14][15].…”

Abstract-In this paper, ultra-wideband characteristics of a hexagonal wide slot antenna with dual band-notched property have been proposed and experimentally investigated. By etching a pair of L-shaped slots and embedding a pair of parallel strip conductors, dual band-notched properties in WiMAX/C-Band satellite application and WLAN band are achieved respectively. Good impedance matching is obtained over a wide band by designing the feed structure with a 50 Ω microstripline loaded by a tuning stub. The stub is proposed to have one hexagonal section and one straight section. The proposed antenna operates over 2.0 GHz-10.7 GHz range, for VSWR ≤ 2, excluding the two rejection bands from 3.4 GHz to 4.3 GHz and 5.12 GHz to 6.4 GHz having rejection level VSWR of 7.84 and 6.5 respectively. The impedance bandwidth of the antenna is 5.35 : 1. The proposed ultrawideband structure also exhibits constant group delay, satisfactory gain and high radiation efficiency in the pass band.

In this paper simple and low profile Wide Band Circular Ring Patch with open ended slot and Rectangular Ground Planar Monopole Antenna is proposed. The proposed antenna is simple to design and offer an effective control over the ultra wideband as well as extra wide band. By controlling the dimension of circular ring patch and optimizing the ground plane, the proposed candidate is suitable form 3.1 to 21 GHz. The simulation is done by using commercially available HL3D software version 15.2 [13]. The simulated VSWR is < 2 over the entire frequency band from 3.1 to 21GHz, approximately 17.9 GHz bandwidth. The antenna is simulated by different radius of the circular ring patch, rectangular ground plane dimension and the gap between the patch and ground. The radiation patterns indicate the suitability of this wireless candidate, like WiFi, WiMAX, X-band and other ultra wideband wireless communication applications.

A novel multi-resonance CPW-fed slot antenna, for UWB applications, is proposed. The proposed antenna consists of a modified fan-shaped radiating stub and a sprocket-shaped ground plane provides a wide usable fractional bandwidth of more than 155% (2.39 -24.53 GHz). By inserting eight pairs of gear-shaped teeth on the sprocket-shaped ground plane, an additional eight resonances are excited and hence much wider impedance bandwidth can be produced. Unlike other antennas reported in the literature to date, the proposed antenna displays a good omnidirectional radiation pattern even at higher frequencies. The designed antenna has a small size of 30 × 30 mm 2 . Simulated and experimental results obtained for this antenna show that it exhibits good radiation behaviour within the UWB frequency range.
