본 발명은 이동 통신 및 무선 통신용 RF 회로에서 PCB 상에 제작된 주변 회로와 세라믹 유전체를 이용한 소자와의 집적화를 위한 기술로 표면 실장용 L-LOOP 형 유전체 내장 금속 도파관 여기 구조에 관한 것이다. 이 여기 구조는 유전체 내장 금속 도파관과 기존 PCB 선로 사이의 임피던스 정합을 고려한 구조이며 표면 실장이 가능하도록 하는 표면 실장용 L-LOOP 형 유전체 내장 금속 도파관 여기 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface-mounted L-LOOP type dielectric embedded metal waveguide excitation structure for integration of peripheral circuits fabricated on a PCB in a RF circuit for mobile communication and wireless communication and a device using a ceramic dielectric. This excitation structure considers impedance matching between a dielectric embedded metal waveguide and a conventional PCB line and relates to a surface mount L-LOOP type dielectric embedded metal waveguide excitation structure for surface mounting.

일반적으로 유전체 내장 금속 도파관의 여기 구조는 도 1에 도시된 바와 같이 외부가 금속 케이스로 형성되고, 금속 케이스 내에 유전체가 내장된 유전체 내장 금속 도파관(1)의 일부분에 동축 케이블(2)의 내부 심선을 삽입 고정시켰다.In general, the excitation structure of the dielectric embedded metal waveguide is formed as a metal case outside as shown in FIG. 1, and the inner core wire of the coaxial cable 2 is connected to a portion of the dielectric embedded metal waveguide 1 having the dielectric embedded therein. Was inserted and fixed.

그러나 이러한 구조로는 동축 케이블의 심선을 유전체에 장하시키기 위해 드릴과 같은 별도의 장비를 이용하여 유전체 내부로 구멍을 내야하는 번거로운 작업이 요구된다. 그리고 신호의 여기를 위해 반드시 동축 콘넥터를 사용하여야 하므로 여기 구조의 특성상 유전체 내장 금속 도파관을 PCB 표면에 실장이 불가능하며, 주변회로와의 연결을 위해서 주변회로 입출력 선로를 동축 케이블로 전환해야 함으로 해서 회로의 집적화가 어려운 문제점이 있다. 또한 전체적인 회로의 크기가 커지며 제작 시 시간과 비용이 추가로 발생하여 회로 양산 시 비 경제적인 문제를 안고 있다.However, such a structure requires a cumbersome task of drilling a hole into the dielectric using a separate device such as a drill to load the core of the coaxial cable to the dielectric. And because the coaxial connector must be used for signal excitation, due to the nature of the excitation structure, it is impossible to mount a metal waveguide with a dielectric built on the surface of the PCB, and the peripheral circuit input and output lines must be converted to coaxial cables for connection to the peripheral circuit. There is a problem that the integration of the difficult. In addition, the overall size of the circuit is larger, and additional time and cost are required for manufacturing, which is an uneconomical problem in mass production of the circuit.

본 발명은 상기와 같은 문제점을 해결하기 위해, PCB 선로로부터 PCB 에 표면 실장된 유전체 내장 금속 도파관 회로로의 신호의 원활한 흐름을 제공할 수 있는 효율적인 여기 구조를 제안하는데 있다.In order to solve the above problems, an object of the present invention is to propose an efficient excitation structure capable of providing a smooth flow of signals from a PCB line to a dielectric embedded metal waveguide circuit surface-mounted on a PCB.

도 2는 본 발명에 따른 자계의 커플링이 가능한 표면 실장용 L-LOOP 형 유전체 내장 금속 도파관 여기 구조를 나타낸 사시도이다.2 is a perspective view showing a surface mount L-LOOP type dielectric built-in metal waveguide excitation structure capable of coupling a magnetic field according to the present invention.

도 2를 참조하면, 본 발명에 따른 자계의 커플링이 가능한 표면 실장용 L-LOOP 형 유전체 내장 금속 도파관 여기 구조는 유전체 내장 금속 도파관(110)의 일 측면에 자계(H-Field)의 커플링이 가능하도록 L-자형으로 도체(120)를 부착하고, 도체(120)의 끝단 부를 유전체 내장 금속 도파관(110)의 저면으로 확장 부착한 후, 저면에 부착된 도체(120)를 PCB(10)에 형성된 선로(20)와 결합시킨다. 여기에서 도체(120)는 마이크로스트립 라인과 같은 도체의 사용이 바람직하다. 이 때 L-LOOP의 모양은 임피던스 정합을 최적화할 수 있도록 설정한다.Referring to FIG. 2, the L-LOOP type dielectric built-in metal waveguide excitation structure for surface mounting according to the present invention enables coupling of a magnetic field to one side of the dielectric embedded metal waveguide 110. After attaching the conductor 120 in an L-shaped shape, and extending the end portion of the conductor 120 to the bottom of the dielectric embedded metal waveguide 110, the conductor 120 attached to the bottom is attached to the PCB 10.

The signal is transmitted to the conductor 120, which is transmitted to the upper end of the L-LOOP to form a magnetic field as shown in FIG. The high frequency magnetic field signal thus formed is finally delivered to the dielectric embedded metal waveguide by magnetic field coupling.
