Abstract
A detection device and method based on an S-shaped microwave transmission line are provided. The detection device includes a metal housing, where the metal housing includes a sensor chamber communicating with an external environment and a circuit board chamber sealed off from the external environment; the sensor chamber includes at least one detection transmission line therein as an external S-shaped microwave transmission line; if there are multiple detection transmission lines, the multiple detection transmission lines are connected in series from end to end to form the external S-shaped microwave transmission line; the circuit board chamber includes an internal S-shaped microwave transmission line therein; and a head end of the external S-shaped microwave transmission line and a head end of the internal S-shaped microwave transmission line serve as microwave signal input terminals.
