In the present work, a compact size, dual-band antenna is proposed for WLAN/WiMAX/LTE 2500/DMB applications. The designed antenna is fed by a 50 Ω coplanar line. The radiating component of the composed antenna consists of radiating strips with half hexagonal and vertical rectangular shapes and square-shaped ground plane which are printed on the same layer. The overall size of the antenna substrate is only 10× 24× 1.6 mm3. The simulated and measured results of the proposed antenna show that it operates in the frequency range from 2.5 GHz to 2.75 GHz and 5.0 GHz to 6.7 GHz, respectively.
