Waveguide conversion device and electronic apparatus

A waveguide conversion device, comprising:

• a waveguide chamber comprising a waveguide transmission chamber and a waveguide back chamber opposite to each other;
• a substrate between the waveguide transmission chamber and the waveguide back chamber, the substrate at least comprising a dielectric substrate;
• a probe in the waveguide chamber and connected to a probe conductive line;
• and
• a mode conversion component on the dielectric substrate and comprising a belt shaped line, a first ground electrode and a second ground electrode, wherein the probe, the probe conductive line and the belt shaped line are connected in sequence, and the probe and the probe conductive line extend into the waveguide transmission chamber,
• wherein the belt shaped line is between and spaced apart from the first ground electrode and the second ground electrode, one end of the belt shaped line is connected to the probe conductive line, and the other end of the belt shaped line is connected to a coplanar waveguide transmission line,
• wherein the probe comprises a probe body and a deformation mechanism at an end of the probe body, and the probe body is configured to change a path of current in the probe,
• wherein the deformation mechanism comprises a plurality of through holes arranged at intervals along a length direction of the probe, and each through hole penetrates through the probe body in a thickness direction of the probe body,
• wherein an end of each of the first ground electrode and the second ground electrode extending into the waveguide transmission chamber is provided with a recess, which opens toward the waveguide transmission chamber and located at a position of the end away from the belt shaped line.
