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 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： 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.

摘要： A resonator, a filter, an oscillator, a duplexer, and a communication apparatus employing these devices have improved efficiency characteristics in confining an electromagnetic field in an opening of an electrode, suppressed current concentration, and minimized conductor loss. Electrode patterns are formed near short-circuited positions in a slot so that the slot will be divided into smaller-width slot lines. Consequently, the efficiency in confining the electromagnetic field is improved, and conductor loss is minimized.

摘要： A resonance device with strengthened coupling between a resonator and a transmission line without reducing an unloaded Q of the resonator. The resonance device includes a micro-strip line as a transmission line, which has a dielectric substrate, a main conductor, and an earth conductor, both of which are formed on the dielectric substrate, and a resonator disposed near the main conductor of the micro-strip line to be electromagnetically coupled thereto. At a part of the main conductor of the micro-strip line where it is coupled to the resonator, an electrodeless portion such as a slit is formed in a direction substantially parallel to a signal-propagating direction.
