摘要： Electrodes (2) and (3) are formed on the front face (1A) and the rear face (1B) of a dielectric substrate (1). Fan-shaped apertures (4A) and (4B) forming a resonator (4) are formed in the electrodes (2) and (3) such that the fan-shaped aperture (4A) opposes the fan-shaped aperture (4B). Accordingly, two parameters, that is, the radius and the central angle, of the fan-shaped apertures (4A) and (4B) can be used to set the resonant frequency of the resonator (4), thus improving the flexibility in design of the resonator (4).

摘要： The invention provides a high frequency filter which can facilitate filter-characteristic adjustments and miniaturization and can obtain an excellent broadband characteristic. In addition, the invention provides a filter device using the high frequency filter, and an electronic apparatus incorporating the same. In this filter, a ground electrode is arranged on one of the main surfaces of a dielectric substrate. On the other main surface thereof there are arranged two or more microstrip lines, and one end of each microstrip line is grounded via a through-hole to form a high frequency filter. The microstrip lines and the shared through-hole constitute microstrip line resonators, which are coupled via the inductance of the through-hole. With this arrangement, there is no need for an additional coupling element. Thus, the size of the high frequency filter can be reduced. Furthermore, since a large coupling coefficient can be obtained, the high frequency filter can have a broadband characteristic.
