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...

Two antenna designs were achieved for dual and wide band operation in wireless systems. One design was realized using a tapered meander slot with a microstrip feed to give dual band operation at 1.8 and 2.4 GHz. In this design both operating frequencies are controlled mainly by the horizontal slot width of the meander and the distance of the microstrip line termination from the slot. The other ...

This paper focuses on the development of a novel single layer dual band proximity fed gap coupled microstrip array antenna. A basic 2x1 microstrip patch array consisting of a pair of rectangular patches which are coupled with a centrally placed microstrip line in the same plane and an arrow headed dumbbell shaped slot in the ground plane is investigated. By using two additional parasitic patche...

AbstactThe study of microstrip patch antennas has made great progress in these days. This is mostly due to their versatility in terms of possible geometries that makes them applicable for many dierent situations. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects like low cost, lighter in weight, low profile, smaller in dimension, low volume...

A design and analysis of a novel proximity-fed printed slot antenna with 3.5/5.5 GHz dual band-notched characteristics are presented. To obtain an ultra-wideband (UWB) response, a circular patch with a rectangular conjunction arm is etched concentrically inside a ground plane aperture. The antenna is proximity-fed by a microstrip line with an open shunt stub on the other side of the substrate. ...
