Abstract :
In this paper, a wideband antenna for mobile terminal is proposed by using a unique direct feed approach. In particular, the approach consists of a cut, a patch and two vertical slots. It is found that both the patch and slot play an important rule in improving the impedance bandwidth of the antenna. An antenna prototype is made and good agreement between the simulated and measured is obtained. The measured impedance bandwidth of the antenna at -6 dB level is from 0.78 to 3.95 GHz, which is sufficient to cover most of the current radio systems.
