DESIGN OF COMPACT PENTA-BAND PRINTED ANTENNA FOR WLAN/WIMAX APPLICATIONS

摘要

This paper presents the compact penta-band printed antenna for the application of wireless communication devices. The antenna consists of a main patch and two sub-patches with a L slot, which is applicable for five operating bands at 1.25, 1.75, 2.45, 3.95, 5.1 GHz for the applications, including WLAN/WiMAX. The radiation pattern and gain is improved by using the concept of Defected Ground Structure (DGS). It Is found that the parameters of an antenna are changed by the variation In the substrate height. The simulated result shows better performance in terms of return loss, radiation pattern, and gain as well.
