Abstract

본 발명은 유전체를 이용한 고주파 필터의 결합구조에 관한 것으로, 상기 유전체블럭(1)의 각각의 공진기(2,3)사이에 그의 결합량을 조절하기 위한 소정크기의 결합량 조절홈(5)이 형성되도록 하며, 또한 상기 결합량 조절홈(5)에 구멍을 유전체 블럭의 하면까지 관통하도록 형성하여 소형화로 제작하면서 공진기 사이의 결합량을 많이 조절할 수 있으며, 치수의 허용오차에 의한 품질계수의 급격한 저하없이 미세한 에러보정이 가능하고, 또한 제조 공정이 간단하여 제조원가를 절감할 수 있는 효과가 있다.The present invention relates to a coupling structure of a high frequency filter using a dielectric, wherein a coupling amount adjusting groove (5) of a predetermined size for adjusting the coupling amount between each resonator (2, 3) of the dielectric block (1) is provided. Also, the coupling amount adjusting groove 5 is formed to penetrate through the hole to the lower surface of the dielectric block, so that the coupling amount between the resonators can be adjusted a lot while being manufactured in a compact size, and the quality factor due to the tolerance of the dimension is abrupt. Fine error correction is possible without deterioration, and the manufacturing process is simple, thereby reducing the manufacturing cost.
