Abstract
A portable telephone has an antenna structure that directs radiated energy away from the user's head. In one embodiment, an external transmission antenna is disposed within a jacket for the portable telephone. A grounded metallic surface is interposed between the antenna and the user's head. The metallic surface is spaced apart from the radiating element of the transmission antenna by one-quarter of the effective wavelength, so as to maximize the reflection of energy away from the user's head.
