Abstract
A portable telephone has an antenna structure that directs radiated energy away from the user's head. In one embodiment, the telephone employs an internal transmission antenna, and a 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. The metallic surface is preferably non-planar to disperse the reflected radiation over a wider area than would be the case with a planar surface. In an alternative embodiment, a pair of spaced-apart planar array transmission antennas are used to preferentially steer the radiated power away from the telephone user's head.
