Claims (1)

  1. 균질이며 단체인 유전체코어에 복수의 중심도체를 형성하여 복수의 유전체 공진기를 구성하고, 상기 중심도체의 상단부로부터 뻗는 금속 피막을 직접 금속화한 주파수 조정용 패턴을 구비한 유전체 필터의 주파수조정방법에 있어서, 상기 주파수 조정용 패턴은 그의 단연부와 외도체와의 거리를 유전체 필터의 길이 방향으로 변화하는 형상으로 형성하고, 이 단연부의 유전체 필터의 길이 방향의 복수개소를 제거하여 주파수의 조정을 하는 것을 특징으로 하는 유전체 필터의 주파수 조정방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
