摘要： An automobile mast antenna used in a state shorter than its resonant state including an FM compensating circuit made only of passive elements and compensating for FM signals and an AM compensating circuit made of active elements that convert high impedance into low impedance and compensating for AM signals. The FM compensating circuit is formed with a primary resonance circuit and a secondary resonance circuit, in which the primary resonance circuit resonates in FM band via impedance of an antenna mast and loading coil which is attached to the antenna mast, and the secondary resonance circuit resonates in FM band via a coil and capacitor. The primary and secondary resonance circuits are coupled by electrostatic capacitance of attachment section of the antenna mast so as to form a double-tuned circuit.

摘要： [Object] To provide a method of manufacturing a helical antenna for satellite communications which has no local bent, etc. in the completed helical coil even though the conductor wire used is of an extremely pliable material, so that a high-quality helical antenna for use in satellite communications is obtained.[Structure] A winding frame 10 in which supporting elements 12 are projected in the form of a cross from the outer circumferential surface of a rod-form base 11 is first obtained. Wedge members 71 through 74, each of which having a configuration of a cylindrical body divided into four sections along its axis, are installed between the supporting elements 12. Then, with the cylindrical surfaces of the wedge members 71 through 74 being used as a winding guide, a conductor wire is wound in helical form through conductor wire installation grooves 13 formed on the edges of the supporting elements 12. Thus, a helical coil 20 is formed. Afterward, the wedge members are removed from the winding frame 10; as a result, an antenna element of a helical antenna suitable for satellite communication is obtained.
