Abstract: A resonator, a filter, and a communication apparatus that can be easily miniaturized even if the resonant frequency is relatively low are provided. Conductor layers are laminated in the state in which they are partially insulated from each other by a dielectric layer. Conductor openings free from any conductor layer in the laminate direction serve as inductive areas, and the portion where the conductor layers oppose each other with the dielectric layer therebetween serves as a capacitive area CA. With this configuration, the resulting resonator serves as a stepped-impedance-structured slot resonator. By increasing the impedance step ratio of the capacitive area to the inductive areas according to this structure, the resonator is miniaturized. Additionally, the conductor loss of the resonator is reduced by suppressing the intrusion of magnetic field energy to the capacitive area. It is thus possible to obtain a small resonator having high Qo.

Abstract: Ring-shaped resonant elements include respectively conductor lines 2a, 2b, and 2c each formed on a substrate 1 along a full one turn of circumferential length of a ring. Each of the conductor lines 2a, 2b, and 2c has two end portions which additionally extend and which are located such that they closely adjoin each other in a width direction. The respective ring-shaped resonant elements are disposed in a concentric fashion. Capacitive parts are formed in areas in which two ends of respective conductor lines are located in close proximity to each other, and the other parts of the respective conductor lines function as inductive parts. Each conductor line operates as a half-wave transmission line whose both ends are electrically open. It is not needed to form a ground electrode on a surface of the substrate opposite to the surface on which the conductor lines are formed. Thus, a resonator can be formed using a very small number of constituent elements. A resonator, a filter, a duplexer, and a communication apparatus having a small size and a high conductor Q-factor can be produced at reasonably low cost.

Abstract: A transmission line, a resonator, a filter, a duplexer, and a communication apparatus efficiently minimize power losses due to edge effects, thereby having superior loss-reduction characteristics. A continuous line and a plurality of thin lines each having a predetermined length and branching from both sides of the continuous line are formed on a dielectric substrate. With this structure, edges of the individual thin lines substantially do not exist, so that losses due to edge effects can be efficiently minimized.

Abstract: A high-frequency circuit device serving as a resonator includes a substrate and an electrode film which is formed on the surface of the substrate and which includes a conductive film and a dielectric film. The conductive film is formed around the substrate such that both ends of the conductive film overlap each other when viewed in a predetermined cross-section of the substrate, and the dielectric film is inserted between both ends of the conductive film. Accordingly, a self-capacitance portion is formed at the overlapped portion of the conductive film, electric-field energy is accumulated therein, and magnetic-field energy is accumulated inside the substrate. With this step impedance structure, the entire high-frequency circuit device can be miniaturized.

Abstract: A filter and a duplexer in which power loss due to the edge effect in resonator lines, is very effectively suppressed, which allow more reduction in overall size to be achieved, and which have desired filter characteristics, and a communication device including either or both of the filter and the duplexer. Three multiple spiral resonator stages are constructed by disposing three multiple spiral lines on the top surface of a dielectric substrate, and forming a ground electrode on the bottom surface thereof. If the first stage is set to be a right-handed spiral resonator, and the second and third stages are set to be left-handed spiral resonators, an attenuation pole is thereby created on the higher frequency side of a pass band.

Abstract: A resonator can provide good loss characteristics by effectively suppressing power losses due to an edge effect. In addition, a filter, a duplexer, and a communication device incorporating the resonator are formed. In the resonator, a plurality of spiral lines are disposed on a surface of a dielectric substrate in such a manner that the inner and outer ends of the lines are aligned respectively along an inner periphery and an outer periphery which are centered around a central point on the substrate so that the lines do not cross each other. With this arrangement, the edge effect in the spiral lines is substantially canceled, by which power losses due to the edge effect can be effectively suppressed.
