Abstract:
An antenna connector for providing impedance matching to an electronic device adapted to receive signals from an antenna, said antenna connector comprising:(a) an antenna; (b) a transmission line adapted to carry a signal from said antenna to the electronic device; (c) a grounding contact adapted to provide an electrical ground for said antenna connector; (d) a transformer adapted to obtain impedance matching between said transmission line and said antenna wherein poles of one coil are connected to said transmission line and to said grounding contact and poles of another coil are connected to said antenna and said grounding contact; and (e) a capacitor connected to said grounding contact and said transformer, said capacitor adapted to provide coupling at FM frequencies while opening said grounding contact at AM frequencies to substantially prevent said transformer from acting to transform impedance in the AM frequencies.
