Broadband transition structure with mixed contact and non-contact protrusions

Abstract

Provided is the broadband transition structure with mixed contact and non-contact protrusions having a first substrate and a second substrate which are adjacent to each other and transmitting a radio wave through a waveguide, in which the first substrate comprises a flat first side, a second side opposite to the first side, a first waveguide provided between the first side and the second side, a third side provided between the first side and the second side as a periphery of the first waveguide, a fourth side connecting the first side and the third side, a plurality of contact protrusions extending from the third side and contacting the second substrate, and a plurality of non-contact protrusions extending from the third side and non-contacting the second substrate.

Dependencies are inferred from the claim text.
