Abstract
A dual band antenna for a radio transceiver includes an inductively loaded conductor of a predetermined length with feedpoint located substantially central of the conductor. Radiator elements terminate the ends of the conductor and a ground plane terminates the radiator elements. An adjustable balanced impedance matching circuit is coupled to the feedpoint. Dual banding elements couple to the impedance matching circuit with a high Q, parallel resonant circuit element. Input and output circuits are also coupled to the dual banding elements. The design minimizes the effect on the antenna operation by the proximity of the user's hands and head since the high impedance portion of the antenna is confined to the center thereof.
