Description
Summary:A compact size planar microstrip‐fed monopole antenna designed for mobile handset applications is proposed. To operate at global system for mobile communication (GSM)/global positioning system/digital communication system/personal communication system/universal mobile telecommunications system and 2.4‐GHz wireless local‐area network bands, a hybrid technique of joining the horizontal section of a T‐monopole to an open‐loop back coupling strip and loading a pair of monopole slot into the ground plane is used. Two operating bands are observed (along 3:1 VSWR) with the lower band covering only the GSM application, while the wide upper operating band covers the remaining applications. The effects on the antenna performances by tuning the various vital parameters have also been studied. © 2011 Wiley Periodicals, Inc.
