摘要： A dielectric filter of which a characteristic is stable without a gastight casing. The dielectric filter's structure is comprised of an input, an output, a dielectric having a plurality of holes extending from a top to a bottom surface thereof, each of the holes being covered with a first conductive material, a second conductive material being electrically connected to the first conductive material at the bottom surface and unconnected to the first conductive material at the top surface, and an insulating weatherproof coating provided on the top surface.

摘要： An LC-type dielectric filter which includes strip lines on a dielectric plate forming distributed constant type resonators. The strip lines and other elements of the filter, such as coupling capacitances are plated onto the dielectric plate as printed circuits to realize a small, high-Q dielectric filter which is suitable for mass-production.

摘要： A microstrip line type resonator includes a rectangular parallelapiped dielectric plate, and a conductive microstrip line disposed on a top surface of the dielectric plate. The microstrip line has opposite ends respectively spaced from front and rear edges of the dielectric plate. The resonator further includes a first grounding layer disposed on an entirety of the bottom surface of the dielectric plate, and a second grounding layer disposed an entirety of the front, rear and side surfaces of the dielectric plate. The first grounding layer is electrically connected to the second grounding layer at the edges of the bottom surface of the dielectric plate. The microstrip line type resonator is a 1/2 wavelength resonator.
