A compact monopole wideband antenna for WiMAX/WLAN/BLUETOOTH/IEEE 802.11y services

A monopole wideband antenna is demonstrated in this paper. The proposed antenna has wideband characteristics which work on three different bands can be used for WiMAX, WLAN, Bluetooth and 802.11y enabled devices. Additional resonances are excited by embedding two L-shaped notches in the ground plane. The return loss at each frequency is S11 <; -20 dB. The various antenna parameters like Return loss, VSWR and Radiation patterns of proposed antenna are presented in the paper.
