Dielectric resonator device |
摘要 |
<p>A dielectric resonator device is disclosed in which characteristics of a plane circuit type dielectric resonator device applicable to miniaturization is included; non- loading Q0f a resonator is increased so as to decrease insertion loss in the case of forming a band pass filter, or the like; reduce changes in filter characteristics with respect to changes in structural dimensions of the length of the resonator, the gap between the resonators, or the like; and increase freedom in adjustment of resonant frequency to enhance production efficiency. In this arrangement, on each main surface of a dielectric plate (1) are disposed an electrode (2) having mutually opposing openings (4a, 4b, 4c), which serve as a rectangular-slot mode dielectric resonator; in which the length of the resonator is longer than the half-wave length in the resonant frequency used so as to resonate in a higher mode. <IMAGE></p> |
