摘要： Herein is revealed a helical antenna apparatus wherein the direction of beam radiation hardly changes even if the frequency in use changes. Two helical antennas which are wound with two conductive wires spirally, respectively, at equal intervals with a specified pitch .alpha. in the form of a cylinder are disposed along the length of the helical antennas so that the axes thereof substantially coincide with each other. By determining the lengths of the feeders of the respective helical antennas appropriately in order to set the phase of supplied power, it is possible to form the beam of signals radiated into space in the shape of conical beam having a directivity oriented obliquely upward. Additionally, it is possible to obtain the conical beam in which the direction of beam radiation does not change even if the frequency in use is changed.

摘要： An antenna system includes a reflector and a primary and a subsidiary array antenna which are disposed in front of an aperture of the reflector so as to be positioned back-to-back with each other. An electric power which is supplied to the primary array antenna is also partly supplied to the subsidiary array antenna after it has been controlled in both phase and amplitude in order that a radiant beam from the subsidiary array antenna compensates for that portion of a secondary radiant beam from the reflector which is blocked by the primary array antenna. For example, a transmission source is connected to the primary array antenna through a coupler and a distributor while the coupler is connected to the subsidiary array antenna through a phase and an amplitude regulator and a distributor. The source may also be connected via the distributor to the primary array antenna formed of a plurality of radiating elements which are respectively connected to corresponding radiating elements of the subsidiary array antenna through couplers and delay lines or feeder lines.
