PROBLEM TO BE SOLVED: To provide a noise cancellation mechanism capable of preventing noise that is generated in a radar device, from being propagated to an antenna.SOLUTION: A noise cancellation mechanism 10 is configured by forming a noise cancellation wire (noise cancellation part) 11 which is formed from a wire-like conductive member electrically separated from an antenna 30 between the antenna 30 on a fitting surface 3A of a window panel 3, for example, and a radar device 20. Thus, most of noise generated in the radar device 20 is made incident to the noise cancellation wire 11 that is brought into a ground potential via a grounding side terminal 15, grounded and discharged before being made incident to the antenna 30 along the fitting surface 3A of the window panel 3. Thus, noise to be propagated in the window panel 3 and reach the antenna 30 is significantly reduced, and performance reduction of the antenna can be surely suppressed.SELECTED DRAWING: Figure 3 |
