A compact triple-band planar monopole antenna for WLAN and WiMAX applications

In this paper, the simulation and measurement results of triple-band planar monopole antenna for application in WLAN and WiMAX bands were presented. The triple-band planar monopole antenna was fabricated on a FR4 substrate. The proposed planar monopole antenna comprised three radiating elements with a longer, middle, and shorter radiating strips. The longer strip controls the lower band of the proposed antenna, while the middle and shorter strips generate the middle and upper bands, respectively. The bandwidth of the proposed triple-band monopole antenna covered the WLAN and WiMAX bands simultaneously.
