PROBLEM TO BE SOLVED: To provide a contact type radar detection device capable of adjusting a waveform structure and allowing a desired frequency band to pass through, and more over, capable of isolating a high pressure low frequency and a high frequency harmonic noise from the frequency band.SOLUTION: A contact type radar device includes housing and antenna components. The inner part of the housing is provided with a high frequency circuit board. The antenna components include: a terminal unit electrically connected to the high frequency circuit board, a matching unit, a signal conduction unit, and a frequency separation device unit. The terminal unit is used for the transmission of detection signals. The matching unit is used for the transmission of signals and electrically connected to the terminal unit. The signal conduction unit is provided so as to correspond to the matching unit, and used for the transmission of the detection signals or the reception of reflection signals. The frequency separation device unit is installed between the matching unit and the signal conduction unit, and has dielectric strength, and enhances a signal noise ratio.SELECTED DRAWING: Figure 2 |
