ABSTRACT
Two printed antennas are probed in this thesis for modern mobile applications: A compact dual-band planar antenna and a wideband printed monopole antenna. The compact dual-band planar antenna consists of a flared monopole with an additional sleeve, this antenna is Finite Ground CPW feeding mechanism and can achieve a dual-band covering DCS-1900/PCS/PHS, WCDMA/IMT-2000, and WLAN. The wideband printed monopole antenna consists of a rectangular monopole and a trapezoid conductor-backed planner for band broadening , this antenna for wireless local area network (WLAN) and world interoperability for microwave access (WiMAX). The analyzed return loss, radiation pattern, and current distribution of this antenna are studied and compare with simulated and measured results for various structures. The experimental results demonstrate the bandwidth and omnidirectional.
Keywords : Compact antenna、dual-band antenna、monopole antenna、DCS-1900、IMT-2000、PCS、PHS、WCDMA
