Printed inset sleeve monopole antennas for dual-band applications

Abstract

In this study, the simple printed monopole antennas with dual-band operation are presented. The proposed antennas without an-v additional metal strips are consisted of the ground shorted inset sleeve for both microstrip and coplanar waveguide type ones. The omnidirectional radiation patterns of two models at two designed frequencies are almost similar to those of a conventional monopole. These printed monopole antennas are very suitable to various dual-band applications for modern communications. Details of the proposed design and experimental results are demonstrated in this article. (C) 2008 Wiley Periodicals, Inc.
