    摘要: An antenna apparatus, a method of manufacturing the same, and a method of designing the same, are provided. A first dielectric layer, first dielectric film, second dielectric layer and second dielectric film are laminated on a flat metal plate in the mentioned order. A radiation element fed through a feeding line is arranged below another radiation element that is not fed through the feeding line. The feeding line forms, along its overall length, a microstrip line having the dielectric layer sandwiched by the feeding line and the flat conductive plate, resulting in no model change from the microstrip line to a triplate line or vice versa, with reduced feeding loss. The thickness of the dielectric layer is so set as to be sufficiently small compared with the used wavelength, to thereby suppress the radiation from discontinuities lying on the microstrip line constituted of the feeding line and flat conductive plate. This eliminates the need for a metal shield plate to prevent unnecessary radiation from the feeding line.

    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 circularly polarized microstrip antenna has a ground plane, a disk-shaped driven element, and a disk-shaped parasitic element. The driven element is located between the ground plane and the parasitic element and is parallel to both of them. The driven element and parasitic element both have diametrically opposed notches, or diametrically opposed projections, or diametrically opposed notches and diametrically opposed projections. The driven element is coupled to a conducting strip that parallels the ground plane to form a microstrip transmission line.

    摘要: A stripline diode phase shifter in which plural hybrid couplers, one for each stage, are connected in series with one another with no bias blocking means disposed between the hybrid couplers to thereby eliminate much loss and unwanted reflections. At least one DC cut is coupled between each of hybrid couplers and a diode loading line. A PIN diode is coupled to a second terminal of the diode loading line. The diode loading line is constructed as a .lambda./4 impedance conversion line section and a diode loading line section coupled in series with the length of the diode loading line section being set such that the phase of reflection voltage from the diode is equal in magnitude but different in sign at the connecting point of the diode loading line section and the .lambda./4 impedance conversion line section.
