    • A high-frequency module has a wiring board including a dielectric substrate, a line conductor that is formed on a first surface of the dielectric substrate, and a first grounding conductor layer that is formed on a second surface opposed to the first surface of the dielectric substrate, and that has a first opening and a second opening disposed around the first opening; and a waveguide that is connected to the second surface, has an opening opposed to the first opening, and is electromagnetically coupled to the line conductor. The wiring board has a vertical choke portion that at least partially extends from the second opening in a direction perpendicular to the second surface. Furhermore, a horizontal choke portion is formed between the wiring board and the waveguide, along the second surface between the opening of the waveguide and the second opening.
    • 高频模块具有布线基板,其包括电介质基板,形成在电介质基板的第一表面上的线路导体和形成在与电介质的第一表面相对的第二表面上的第一接地导体层 基板,并且具有设置在第一开口周围的第一开口和第二开口; 并且连接到第二表面的波导具有与第一开口相对的开口,并且与线路导体电磁耦合。 布线板具有垂直的扼流部分,其在垂直于第二表面的方向上从第二开口至少部分地延伸。 此外,沿着波导的开口和第二开口之间的第二表面,在布线板和波导之间形成水平的扼流部。
