摘要： A delay line structure includes a serpentine delay line, a first grounding guard trace and a second grounding guard trace. The serpentine delay line is disposed in a layout layer of a substrate in a manner of extending from an input end to an out put end in serpentine so as to form at least a first coupling area having a first opening toward a first direction and at least a second coupling area having a second opening toward a direction opposite to the first direction. The first grounding guard trace is disposed in the layout layer in a manner of extending from the first opening toward the first coupling area and an end of the first grounding guard trace close to the first opening is electrically connected to the grounding circuit through a first via. The second grounding guard trace is disposed in the layout layer in a manner of extending from the second opening toward the second coupling area and an end of the second grounding guard trace close to the second opening is electrically connected to the grounding circuit through a second via.
