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.
