<p>Provided are a high-frequency substrate which has reduced size and suppresses unnecessary radiation from a hybrid circuit, and a high-frequency module. The high-frequency substrate is provided with a first waveguide, a second waveguide, a first conversion section and a second conversion section. The first waveguide is composed of a laminated waveguide tube including a first conductor layer. The second waveguide is electromagnetically connected to the first waveguide through an opening formed on the first conductor layer and configures the hybrid circuit. The first and the second conversion sections are electromagnetically or electrically connected to the first and the second waveguides, respectively, and convert signal transmission mode.</p> |
