Abstract
A dielectric resonator device with a higher Q and a lower cost and which makes it possible to effect spatial coupling between predetermined dielectric columns of adjacent dielectric resonators without using any special coupling loop. One disclosed dielectric resonator device includes a first magnetic-field-coupling window for effecting magnetic field coupling between a first pair and a second pair of dielectric columns and a second magnetic-field-coupling window for effecting magnetic field coupling between a third pair of dielectric columns. Due to this construction, it is possible to successively effect magnetic field coupling between predetermined dielectric columns of adjacent dielectric resonators solely by spatial magnetic coupling, without having to employ any partition or special coupling loop. Further, this construction facilitates the provision of characteristics-adjusting holes perpendicularly to the plane made by each composite dielectric column.
