ANTENNA APPARATUS FOR MILIMETER WAVE COMMUNICATION HAVING WAVEGUIDE WHICH DIELECTRIC INSERTED INTO

摘要

The present invention relates to a millimeter wave communication antenna device having a waveguide in which a dielectric is inserted, comprising: an antenna board with multiple antenna elements arranged on one side; and a transceiver module substrate stacked between an antenna substrate and an interface substrate having a predetermined thickness, and disposed to interact with the antenna element. In the interface substrate, at least one waveguide for signal connection between the transceiver module substrate and the antenna element is formed to penetrate in the thickness direction, so as to provide an advantage of minimizing the signal loss due to the increase of the thickness of the substrate.
