الملخص الإنجليزي

Ultra-Wideband (UWB) communication systems provide an important means for short range high data rate wireless transmission between electronic devices.

Portable devices and in particular, mobile handsets, have the potential to harness the unprecedented connectivity associated with UWB’s high speed, low power data transfer.

In this thesis designs a printed monopole antennas with reduced ground plane have been presented as candidates for use in ultra wideband applications with WLAN band isolation.

All of the proposed antennas are based on the monopole antenna structure having a nearly square shape radiating structure with E-shaped slot embedded in it .

A 50 Ω microstrep line is used to feed the proposed antenna.

The proposed antennas have been supposed to be etched using a substrate with relative permittivity (εr ) of 4.6 and thickness of 1.6 mm.

Modeling and performance evaluation of the proposed designed antenna have been carried out using two techniques a method of moment based EM(Electromagnetic) simulator IE3D and finite integration technique simulator CST(Computer Simulation Technology).

Result show that the proposed antenna has a compact size of 20mm×25mm.The resulting antenna has been found to possess an impedance bandwidth, for voltage standing-wave ratio less than 2, exceeding what is required for ultra wideband applications.

IE3D and CST Simulations results show that the lower frequency is primarily determined by the monopole square perimeter, while the slot has an effective role to allocate the position of the band notch.

A parametric study has been conducted to provide more understanding of the effects of antenna parameters on its performance.

Besides, the reasonable performance, the simple structure of the proposed antenna will make it an attractive choice for antenna designers.
