This article presents the design, simulation and testing of an Ultra Wide Band (UWB) planar monopole antenna with WLAN band-notch characteristic. The proposed antenna consists, the combination of planar monopole antenna with partial ground and a pair of AMC structures. The AMC structure used for the design is mushroom-like. Design equation of EBG parameters is also proposed for FR4 substrate us...

Ultra−WideBand (UWB) technology was approved by the Federal Communications Commission (FCC) in February 2002 (FCC, 2002). According to the FCC regulations, the frequency band from 3.1 to 10.6 GHz can be used for short−range and high speed wireless communications systems. This recent allocation of a very wide spectrum of frequencies for the devices uses, with effective isotropic radiated power (...

In this paper, a new compact design of the printed monopole antenna has been presented. The single layered antenna has been designed to resonate in wideband frequency for UMTS, LTE and WLAN with enhanced bandwidth of more than 1.25GHz.The antenna has a simple structure consisting of a Tshaped and parasitic element in the ground plane. The proposed antenna has a low profile and can easily be fed...

This article gives a parametric study on strawberry-shaped monopole antennas for ultra-wideband (UWB) systems. The antenna design consisted of three different steps to structure the strawberry radiated antenna. scheduled was simulated an FR4 substrate in low profile UWB applications. total physical dimension is 26 mm×26 mm×1.6 mm, corresponding centre frequency 7.5 GHz. fed via coplanar wavegui...

A practical normal-mode helical antenna array together with a new method for the compensation of mutual coupling effect is proposed for the efficient adaptive nulling of interferences in a mobile communication environment. The helical antenna array is shown to be able to generate deeper nulls than an equivalent monopole antenna array in the presence of mutual coupling effect. The helical antenn...

A method to reduce the specific absorption rate(SAR) of the antenna for WiMAX mobile communication is proposed in this paper. The SAR reduction is achieved by miniaturizing the physical size of the antenna for the given resonance frequency by devising a metamaterial-composite rightand left-handed(CRLH) configuration-based radiator much smaller than the quarter-guided wavelength adopted a lot in...

This paper presents a modal-expansion analysis of the electromagnetically coupled coaxial dipole antenna. The analysis of the antenna problem is initially simplified using the even-odd mode excitation and then the resultant half structure is divided into two parts; one is the characterization of a coaxial feeding network and the other is the modeling of a sleeve monopole antenna driven by a coa...
