A NOVEL (Q-SLOT) MULTI BAND ANTENNA FOR WIRELESS COMMUNICATIONS

Abstract

In this research, the proposed antenna is a novel design made out of (Q- slot) that fed by step impedance micro strip line open mouth ended. The proposed antenna is intended to work at four bandwidth frequency groups meet the specifications of DO,1xRTT-3G (1xRTT is a data transmission system used on CDMA networks that allows for connection speeds of up to a theoretical limit of 144kbps), Wi-Fi-IEEE802.11e (local area wireless computer networking technology) and WiMAXIEEE802.16m (Worldwide Interoperability for Microwave Access) communications. The surface current distribution at resonant frequencies and the effect of varying the dimensions of parameters had been studied carefully in this research to enhanced the performance of resonant frequency. Also the radiation patterns in (E-plane) and (H-plane) for the antenna had been studied. This document is a live template.
