ABSTRACT:
A dual radiator galvanically coupled antenna for a portable communication device. The antenna includes separate elongate and upper radiators that respectively galvanically couple to phone circuits in extended and retracted states. An insulator, preferably thermoplastic, mechanically connects and electrically separates the elongate and upper radiators. In a preferred embodiment, a shaped conductor provides an electrode with a cup having a thinned wall which crimps onto an end of an upper helical radiator to make electrical contact thereto. The shaped conductor also forms an exposed galvanic electrical contact, and an enlarged knurled portion for mechanical connection to the insulator. A separate enlarged galvanic contact is formed at a terminal end of the elongate conductor. An additional preferred embodiment includes an upper rod galvanically coupled to the electrode and electrically parallel with the helical radiator.
