Abstract:
A method for manufacturing a mode converter including a substrate that is a single member and includes a first main surface, a second main surface opposite to the first main surface, and a micro hole which is formed in the first main surface and has a predetermined depth, grounding conductor layers that are formed on the first main surface and the second main surface, a plane circuit that is formed on the first main surface and is configured to transmit a high-frequency signal, and a pin that is formed so as to cover an inner surface of the micro hole and is electrically connected to the plane circuit, the method includes: irradiating the substrate with laser light and thereby forming a first modified portion to a desired depth from one main surface of the substrate; removing the first modified portion and thereby forming the micro hose; and filling the micro hole with a conductive material and thereby form the pin.
Abstract:
An electronic device provided with a plurality of circuit boards uses a support member for supporting the circuit boards as the transmission path of a wireless signal. For example, the electronic device is provided with a first printed circuit board for processing a millimeter-wave signal, a second printed circuit board which is signal-coupled to the printed circuit board and receives the millimeter-wave signal to subject the received signal to signal processing, and a waveguide which is disposed with a predetermined dielectric constant between the printed circuit boards, wherein the waveguide constitutes the dielectric transmission path, and the waveguide supports the printed circuit boards. This configuration makes it possible to receive the electromagnetic wave based on a millimeter-wave signal radiated from one end of the waveguide constituting the dielectric transmission path, at the other end thereof.
Abstract:
