Antenna assembly for a portable transceiver

摘要

An antenna assembly for use with a portable transceiver provides improved communication between the portable transceiver and a base station. A novel antenna assembly is created wherein the radiating portion is elevated above the handset by combining a half wavelength sleeve dipole antenna with a coaxial line section followed by a quarter wavelength choke. Such a configuration reduces the antenna-housing interaction. The quarter wavelength choke prevents the coaxial transmission line from radiating RF energy, and therefore limits the radiation to the sleeve dipole portion of the antenna assembly.
