  • Patent number: 4590614
    Abstract: A dipole antenna for a portable radio is contained completely within the insulated housing (10) of the transceiver. The dipole antenna is formed as two conductive surfaces (12, 13) electrically isolated from each other but disposed on the same printed circuit board (11) of the transceiver circuit which supports the circuit modules (14, 15). The two dipole halves are connected to each other by means of a dipole tuning circuit (29). The conductive tracks (23, 26, 27) of the transceiver circuit are interrupted at a location which divides as few tracks as possible. The interrupted tracks are bridged together by high-impedance resistors (22).
