Abstract
A wireless terminal comprises a ground conductor () and a transceiver coupled to an antenna feed, the antenna feed being coupled directly to the ground conductor (). In one embodiment the ground conductor is a conducting case (). The coupling may be via a parallel plate capacitor () formed by a plate () and a surface () of the case (). The case () acts as an efficient, wideband radiator, eliminating the need for a separate antenna. In a modification of this embodiment a slot () is provided to increase the resistance of the case () as seen by the transceiver, thereby increasing the radiating bandwidth of the terminal.
