“…The wider slot gives more bandwidth, and the optimum feed structure gives good impedance matching [11]. The CPW feed line with various possible patch shapes available in the literature such as 'T', cross, forklike, volcano and square are used to give wide bandwidth [12][13][14][15]. The proposed antenna in this paper designed with a compact rectangular slot and a cross like structure at the anterior portion of the feed.…”

Abstract-Design and analysis of a compact coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna is presented in this paper. The antenna consists of a rectangular slot with cross like structure at the anterior portion of the feed which acts as tuning stub. The CPW feed is designed for 50 Ω impedance. The physical dimension of the proposed antenna is 19 mm (length) × 20 mm (width) × 1.6 mm (thickness), and the electrical size is 0.3λ l (length) × 0.32λ l (width) (f l = 4.8 GHz). The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. An extensive analysis of the proposed antenna in the frequency and time domains is presented. The antenna was fabricated with FR4 substrate and characterized by measuring return loss, radiation pattern (5.5 GHz) and gain. The measured results are appreciably in good agreement with the simulated ones. A better impedance bandwidth is obtained from 4.8 GHz to 12.8 GHz that constitutes a fractional bandwidth of 90% with return loss less than or equal to −10 dB (VSWR ≤ 2). Time domain analysis of the antenna is also performed, which witnessed the linear phase and less distortion. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication that may be built for any wireless UWB device applications.

“…As a result of its intrinsic wide bandwidth, good isolation characteristics due to its relatively low coupling through surface waves, and negligible radiation from feeding network, the printed slot antenna emerges as an excellent candidate for the newer generation of wireless antennas. Recently, a number of experimental investigations on the impedance bandwidth of printed slot antennas have been reported by various authors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The proposed methodologies include modifying the feeding structure [1][2][3][4][5][6][7], the radiation aperture [8], introducing some tuning stubs into the radiating aperture [9][10][11][12], and feeding at slot edge with a microstrip line to create a second resonance [13][14][15].…”

Abstract-A new technique is proposed to increase the bandwidth (BW) of slot antenna operated at 2.4 GHz and 5 GHz, over the industrial-scientific-medical (ISM) bands and the Hiperlan2 bands. By splitting two side slots of the Z-like slot antenna into two or three fingers, several additional resonances can be created. By properly arranging the geometry of the feeding structure in the multi-slot region, the double-slot and triple-slot antennas have respectively 2.0 and 3.2 times wider bandwidth than the single Z-slot antenna. According to the results, the proposed triple-slot antenna can provide two separated impedance bandwidths of 672 Hz (about 28.3% centered at 2.4 GHz band) and 2752 MHz (about 53.5% centered at 5.2 GHz band), making it easily cover the required bandwidths for WLAN operation in the 2.4 GHz band and 5.2/5.8 GHz bands.

In this paper, a novel, small, and compact planar antenna for ultra-wideband (UWB) applications is proposed. The antenna is an extension of microstrip slot antenna technology. To achieve ultra-wideband characteristics, a tapered microstrip fork-shaped stub has been employed. A symmetric polygon wide slot has been placed on the antenna ground. The design was investigated numerically to obtain proper dimensions for the antenna and a prototype was constructed. The return loss, pattern and gain of the prototype antenna have been measured. The transient pulse signal fidelity has also been investigated by finite-difference timedomain (FDTD) method. Experimental results show that the proposed antenna design has promising characteristics for UWB applications.
