    摘要： A resonator, a filter, and a duplexer are provided which are capable of very effectively suppressing the power loss caused by the edge effect, and which allow a great reduction in the overall size to be achieved. Also, a communication device including the above-mentioned filter or duplexer is provided. A ground electrode is formed over the bottom surface of a dielectric substrate, and a multiple spiral line pattern is formed on the top surface thereof. A radial line pattern is further formed on this surface with an insulation layer interposed therebetween. By thus disposing the radial pattern adjacently to the multiple spiral resonator constituted of the above-mentioned multiple spiral line, an electrostatic capacitance is added to the multiple spiral resonator. This reduces the occupation area of the resonator on the substrate, and improves the loss reduction effect.

    摘要： 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.

    摘要： A filter, duplexer, and a communications device have significantly reduced power loss due to the edge effect, and the coupling structure between a resonator and an input or output terminal does not negatively affect the reduction of power loss. A plurality of resonators is provided on a dielectric substrate. Each of the resonators is constituted of a multiple spiral transmission line assembly. At the centers of the multiple spiral transmission assemblies at the input end and the output end, respectively, there are formed coupling pads which are capacitively coupled to associated multiple transmission line assemblies.

    摘要： 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.
