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 ...

In this paper, we present multiple L slots antenna for WIMAX and WLAN applications. wideband microstrip patch antenna for wireless applications. The coplanar waveguide fed microstrip patch antenna comprises of four rectangular patch array each embedded on three L slots and a Plus slot either on the patch or on the ground plane or on both the patch and the ground plane. The design results in red...

A Coplanar Waveguide Fed ultra wide band (UWB) slotted Hexagonal patch antenna which finds application in wireless communication is presented here. It was designed to operate in the UWB range ( 3.1GHz to 10.60GHz). The antenna presented here is designed on FR4 substrate with loss tangent δ=0.0025 and dielectric constant 4.4. The dimension of the proposed antenna is 34 X 29 X 1.6 mm. The fundame...

We report on a metamolecule antenna, based on a fish-scale design but augmented with two split-ring resonators (SRRs) placed within the fish-scale loops. The properties of the antenna resonator, with and without additional SRRs, were examined using finite element method simulations (COMSOL Multiphysics). The simulation findings were subsequently confirmed experimentally, using a vector network ...

This paper shows the design of a fractal patch antenna, which uses a unique fractal geometry known as Pythagoras tree with co-planer waveguide (CPW) feeding. The antenna has been designed for dual band operation at the WLAN/WiMAX (2.4 GHz) and WiMAX (3.5 GHz) for ultra-wide bandwidth applications. The antenna was simulated using CST Microwave Studio. The fabricated antenna’s measurement results...

Authors have developed various types of single-layer slotted waveguide arrays with simple structure and high mass-productivity. Those arrays have been successfully applied to relatively narrowband commercial services for satellite broadcast reception in 12 GHz band and wireless IP access at home in 26 GHz band etc. However, one weak point of that antenna is that the bandwidth of the antenna gai...

A novel manufacturing procedure for the fabrication of ultra-wideband cavity-backed substrate integrated waveguide antennas on textile substrates is proposed. The antenna cavity is constructed using a single laser-cut electrotextile patch, which is folded around the substrate. Electrotextile slabs protruding from the laser-cut patch are then vertically folded and glued to form the antenna cavit...

A new dual band and dual polarized slot antenna is designed at x band, using longitudinal and transverse slots on the broad wall of the substrate integrated waveguide. The two resonances are completely apart in a low cross polarization level at both sets. antenna has a minimum radiation efficiency of 80% in both bands.

The characteristics of dielectric backed planar conducting layers of arbitrarily shaped in a rectangular waveguide are calculated by means of coupled integral equation technique (CIET) which accurately takes higher order mode interactions. Equivalent structures for the accurate analysis whole structure are introduced in which magnetic surface currents are identified as the unknowns at the apert...

A novel narrow compact CPW-fed rectangular monopole patch antenna is proposed for UMTS band. The purpose is to design a new narrow compact antenna structure by using of a new CPW feeding technique. The most significant characteristics of proposed antenna are: narrow compact size of 67.3×7.8×0.762 mm and very simple structure. The proposed low profile antenna is printed on a single layer dielect...
