    摘要： The invention provides an antenna in which a signal is directly transferred from a planar dielectric transmission line to a primary radiator without having to perform transmission mode conversion from the planar dielectric transmission mode to another mode such as a coplanar transmission mode, a microstrip transmission mode, or a waveguide transmission mode thereby eliminating the transmission loss which would otherwise occur due to the transmission mode conversion. A dielectric resonator is disposed in the vicinity of the end of the planar dielectric transmission line PDTL formed between two slots disposed on both sides of a dielectric plate. Furthermore, a slotted plate, a lens supporting base, and a dielectric lens are disposed one on another.

    摘要： A planar dielectric integrated circuit is provided such that energy conversion loss between a planar dielectric line and electronic components is small and that impedance matching between them can be easily obtained. A planar dielectric line is provided by causing two slots to oppose each other with a dielectric plate interposed in between, a slot line and line-conversion conductor patterns are provided in the end portions of the planar dielectric line, and an FET is disposed in such a manner as to be extended over the slot line.

    摘要： A nonradiative planar dielectric line exhibits low transmission losses and is easily connectable to electronic components. A first slot is provided between two electrodes on a first main surface of a dielectric plate. A second slot is provided between two electrodes on a second main surface of the dielectric plate. A first conductor is electrically connected to the electrodes on the first main surface and also covers the first slot. A second conductor is electrically connected to the electrodes on the second main surface and also covers the second slot. An integrated circuit using the above type of dielectric line is also provided. Thus, apparatuses using the above dielectric lines or integrated circuits are miniaturized.

    摘要： Electrodes are formed on both top and bottom surfaces of a dielectric plate and grounded coplanar lines, as transmission lines, are formed on the top surface of the dielectric plate. A plurality of micro-strip lines, each composed of high-impedance lines and low-impedance lines alternately connected in series, is arranged at a pitch shorter than the wavelength of a wave traveling along the grounded coplanar lines. A spurious mode propagation blocking circuit thus constructed prevents a spurious mode wave, such as a parallel-plate mode, from traveling.

    摘要： A radio-frequency radiation source comprises electrodes containing opposing electrodeless parts formed on both sides of a dielectric plate in which the electrodeless parts are made to function as a dielectric resonator, a slit formed in the electrodeless part, and a switching element mounted over the slit. Further, a transmission line coupled to the dielectric resonator is provided. As constructed this way, the resonance frequency of the resonator is switched by turn-on and turn-off of the switching element. When the resonator resonates with the frequency of a signal propagated through the transmission line, the energy of the electromagnetic field is radiated to the outside through a slot.
