    摘要： A dielectric filter for a high frequency band includes a plurality of resonators formed by boring a plurality of through holes between the oppositely disposed end surfaces of a dielectric block in parallel with each other and arranging internal conductors on the inner peripheral surfaces of the respective through holes and an external conductor formed on a substantial portion of the outer peripheral surface of the dielectric block. A non-conductive region is formed on the short-circuit end surface and extends in parallel with the direction connecting the resonators, thereby the filter can be controlled satisfactorily for coupling the dielectric coaxial resonators and have a reduced height.

    摘要： A dielectric antenna includes a plate-shaped dielectric substrate, a radiation electrode provided on a first main surface of the dielectric substrate so as to cover the first main surface except for a peripheral portion thereof, and a ground electrode formed on the entirety of a second main surface of the dielectric substrate. A feed electrode extends through the dielectric substrate from the first main surface to the second main surface. A feed point of the feed electrode is electrically connected to the radiation electrode. A plurality of through-hole electrodes providing an electrical shield are formed in a peripheral portion of the dielectric substrate so as to surround the radiation electrode, the through-hole electrodes being connected to the ground electrode. Alternatively, instead of the through-hole electrodes, the dielectric antenna may include a shield electrode formed on a side surface of the dielectric substrate and connected to the ground electrode.
