International Journal of Communication
A new microstrip-fed monopole antenna with simple planar structure of size 24×28×1.6 mm 3 is presented for ultra-wideband (UWB) applications. The antenna structure consists of V-shaped patch, microstrip-fed line and partial ground plane structure. With the inclusion of U-shaped slot on to the patch, a frequency notched characteristics is achieved which can reject the frequency band of 5.15-5.825 GHz. The effects of dimensional parameters on antenna performance such as length and width of U shaped slot, size of the ground plane have been investigated through a parametric study and design results from parametric simulations are presented. The electric current distributions on the patch are also exhibited in this paper. Simulation results confirm that the presented antenna has a large bandwidth below (S11≤ -10 dB) covering the ultrawideband frequency range of (3.15-13.2 GHz) with band notch characteristics at WLAN band. The proposed antenna creates a monopole like pattern in the E-plane and omnidirectional radiation pattern in the H-plane.
Design and analysis of ultra wide band planar monopole antenna

A novel two layered UWB antenna is proposed and designed to resonate at the full range of UWB frequencies' spectrums from 3.1 GHz up to 10.6 GHz, well below -14.0dB reference levels of return loss. The size of the UWB antenna is small, with width of 31.0 mm and length of 25.0 mm, and the two layers of FR4 board thickness are 0.5 mm (top layer) and 1.6 mm (bottom layer).The antenna radiates omni-directionally with different intensities at different directivities within the UWB frequency spectrums. The dual layered configuration gives the antenna additional options of being integrated with additional structures in order to perform a band rejection of a certain targeted band of frequencies, if required. The UWB antenna has also been fabricated using the same dimensions on a single layer 1.6 mm thick FR4 board and it still gives similar excellent performance.
Compact Planar Rectangular Monopole Patch Antenna for Ultra-wideband Application
A compact monopole microstrip rectangular patch antenna having defected ground plane(DGP) with notches is presented in this paper. Ultra-wide band (UWB) patch antenna is feed by microstrip line feed. Parametric study have been conducted by changing the gap distance between radiating patch and DGP and changing the feed position. Optimum results are observed when gap between the radiating patch and DGP is 0.5mm and for offset feeding of microstrip feed line. The obtained reflection coefficient is less than -10dB for a frequency range of 3GHz to 10.66 GHz. The antenna has been designed on a FR4 substrate with dielectric constant єr = 4.4, loss tangent (tan δ) = 0.02.The radiation pattern is directional in E-plane and nearly omnidirectional in H-plane. Efficiency decreases at the higher frequency edge due to the lossy substrate. The UWB antenna is simulated using CAD FEKO 6.2 suit electromagnetic simulator using MoM (Method of Moment).

A new microstrip-fed planar monopole antenna is presented for ultra-wideband (UWB) communication systems. The antenna structure consists of a dome-topped, bowl-shaped patch with a truncated ground plane structure. The ground plane is predominately tapered and includes a notch below the feed-line in the vicinity of the patch. The effects of dimensional parameters on the performance of the antenna have been investigated through a parametric study. Current density distribution on the antenna was also computed to gain a better insight of its behaviour. The antenna performance is validated through measurement, including its radiation patterns. The measured impedance bandwidth of the proposed antenna for |S 11 | ≤ 2 10 dB is 10.35 GHz (2.65-13.0 GHz), constituting 132% impedance bandwidth. The fabricated antenna has a compact size of 18 × 20 × 1.6 mm 3 . Additional features that make the antenna a suitable candidate for UWB systems are its simple configuration, compactness and low fabrication cost.

European Journal of Scientific Research
In this study, a simple and compact ultra-wideband (UWB) patch antenna with rectangular slot is presented. The fabricated antenna consists of a rectangular patch tapered from a microstrip feeding structure and a truncated ground plane. The proposed antenna is etched onto a FR4 printed circuit board (PCB) with an overall size of 28 mm × 29 mm × 1.6 mm. Simulated and experimental results are compared and are shown to be in good agreement. Experimental results indicate that the antenna achieved an UWB impedance bandwidth (S 11 < -10 dB) ranges from 3.8 to 12 GHz. The small antenna exhibits a good voltage standing wave ratio (VSWR) performance and its E-and H-plane radiation patterns are stable over the UWB frequency range. The simulated result shows that the designed antenna can achieve a gain between 1.5 and 4.5 dBi against frequency. Besides, the group delay is less than 0.4 ns over the operating frequency band. These characteristics make the designed antenna suitable for various UWB applications.
