摘要： An antenna apparatus in which a combination of rectangular waveguides 9a and 10a and a combination of rectangular waveguides 9b and 10b are disposed bilateral symmetrically to each other, and a waveguide orthomode transducer 13 is disposed above a waveguide orthomode transducer 8 is provided. Therefore, the profile of the antenna apparatus can be reduced and the stability of installation of the antenna apparatus can be improved without impairing the electric characteristics of the antenna apparatus. Since the antenna apparatus has a bilateral symmetric structure, it excels in weight balance and offers stable performance from the viewpoint of mechanism.

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： A composite antenna apparatus comprising a balun connected to an inner conductor at the upper end of a coaxial line 11, one end of a helical element formed by a pair of wire conductors is connected to the balun, the other end is wound symmetrically around the coaxial line using the the coaxial line as a center so as to face the balun and is connected to the outer conductor 13 at the lower end of the coaxial line. The provision of an outer conductor connecting terminal connected to the outer conductor and an inner conductor connecting terminal connected to the inner conductor at the lower end of the coaxial line, allows the formation, on the same axis, of a helical antenna fed by the coaxial line via the helical element and a monopole antenna formed by the outer conductor of the coaxial line. Thereby equivalent gain in the horizontal plane and a reduction in the occupied volume is achieved.

摘要： A disk-shaped reflecting plate 3 for reflecting an electric wave emitted out of an aperture 1a of a circular waveguide 1 is placed a location which is just opposite to the aperture 1a of the circular waveguide 1, and a ring-shaped waveguide 4 for shaping the radiation characteristic of the electric wave reflected by the disk-shaped reflecting plate 3 to a rotational symmetrical radiation characteristic is disposed around the perimeter of the disk-shaped reflecting plate 3. Thereby, even when many grooves 4a need to be formed in order to make the electric wave have a rotational symmetrical radiation characteristic, it is not necessary to increase the size of the disk-shaped reflecting plate 3 in the direction of its radius.
