  • Antenna
    Patent number: 6952186
    Abstract: A helical antenna capable of operating at a plurality of different resonant frequencies. The helical antenna has a first helical antenna element, a second helical antenna element arranged coaxially with the first helical antenna element and coupled to the first helical antenna element through capacitive coupling, and a metal connection directly connected only to the first helical antenna element to fed the helical antenna. The first helical antenna element is fed through one end thereof to function as a quarter-wave antenna. The second helical antenna element is fed through capacitive coupling to function as a half-wave antenna.
