More Information
Summary:The present disclosure provides a radar device, which includes: a circuit board provided inside a housing having an upper side open, and on which an RF element is mounted on an upper surface; and a cavity having an open lower side and coupled to the upper surface of the circuit board so that the cavity accommodates the RF element, wherein the cavity includes a coupling portion extending downward in a region of a surface coupled to the circuit board, and the coupling portion is inserted into a coupling hole formed in the circuit board to contact a ground plane of the circuit board. Accordingly, charge conducted to the cavity can be removed. 본 개시는 상측이 개구된 하우징 내부에 구비되며, 상측면에 RF 소자가 실장되는 회로기판 및 하측이 개구되어 RF 소자가 내부에 포함되도록 회로기판의 상측면에 결합되는 캐비티(cavity)를 포함하되, 캐비티는 회로기판과 결합되는 면의 일 영역에 수직 하방으로 연장 형성되는 결합부를 포함하고, 결합부는 회로기판에 형성된 결합홀에 삽입되어 회로기판의 접지면에 접촉되는 레이더 장치를 제공한다.
