    摘要： A radio tag communication system, when a plurality of RW apparatuses are arranged in such a manner that communication areas of adjacent RW apparatuses overlap one another, makes the polarized waves of the adjacent RW apparatuses orthogonal to each other, and causes the tag to switch the polarization direction with the movement of the tag. This makes it possible to prevent signal interference even when the communication areas are expanded.

    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 planar antenna apparatus adapted to excite a small radiating element by electromagnetic coupling is provided. The antenna apparatus has a triplate line including ground conductor plates formed on the upper and lower surfaces of a dielectric substrate and a feed line sandwiched by the ground conductor plates. A coupling hole is formed through one of the ground conductor plates, and a mechanism is provided near the coupling hole for electrically interconnecting the two ground conductor plates. A radiating section coupled to the feed line through the coupling hole has one end grounded to form a short patch antenna. The short patch antenna has a size substantially half the size of a patch antenna. Also, the connecting mechanism prevents unnecessary coupling.

    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.
