Scanning apparatus and security-inspection device with the same

Abstract

The present disclosure relates to a scanning apparatus and a security-inspection device with the same. The scanning apparatus include: at least one millimeter-wave transreceiving antenna module, wherein the millimeter-wave transreceiving antenna module include a plurality of millimeter-wave transreceiving antenna units each having a signal terminal facing the predetermined scanning area, and a dustproof film covering the signal terminal of each of the millimeter-wave transreceiving antenna units. The scanning mechanism is simple in structure, more convenient for maintenance, and has a lower cost. When each millimeter-wave transceiving antenna unit emits and receives millimeter waves, the millimeter waves pass through the dustproof film without passing through the organic glass, and the attenuation of the millimeter wave signal is small, thereby improving the 3D imaging effect of the security-inspection device.
