Millimeter wave antenna and millimeter wave transceiver device suitable for high pressure environment

Abstract

The application discloses a millimeter wave antenna and a millimeter wave transceiver device suitable for a high-pressure environment. The millimeter wave antenna comprises a multilayer dielectric substrate, a radiation patch arranged on the surface of the multilayer dielectric substrate, a first feeding structure comprising a vertical probe penetrating through the multilayer dielectric substrate and used for exciting the radiation patch in a first polarization direction, and a second feeding structure comprising a slot hole arranged in the multilayer dielectric substrate and a horizontal microstrip line electromagnetically coupled with the slot hole and used for exciting the radiation patch in a second polarization direction orthogonal to the first polarization direction. The vertical probe and the horizontal microstrip line are arranged in an orthogonal direction on a plane parallel to the radiation patch, and the vertical probe and the slot hole are arranged in a staggered manner on the plane. The application integrates two feeding structures with orthogonal polarization characteristics on the same radiation patch, and optimizes the spatial layout, so that a high-isolation transceiving channel in a compact volume is realized.
