Abstract:
1. A high frequency package comprising: a metal base having a mounting part of a high frequency electronic component on one surface, and a through hole disposed to be adjacent to the mounting part, an opening on one side of the through hole being connected with a waveguide; and a high frequency line-to-waveguide conversion substrate joined on an opening on another side of the through hole, the high frequency line-to-waveguide conversion substrate including: a high frequency line including: a frame ground conductor formed on another surface of the dielectric substrate in a shape conforming to an opening on another side of the through hole so as to be opposite to the end of the high frequency line conductor on the center part side; a slot provided on the same surface ground conductor and formed to be orthogonal to the end of the high frequency line conductor on the center part side and coupled to the high frequency line in terms of high frequency; and a connection conductor for connecting the same surface ground conductor and the frame ground conductors, wherein the high frequency line-to-waveguide conversion substrate is joined on the other side of the through hole such that the high frequency line is positioned on a side of the mounting part and the frame ground conductor is made to conform to the opening on the other side of the through hole.
