Abstract
A signal transmission apparatus includes: a transmission section adapted to transmit a transmission object signal as a radio wave; a reception section adapted to receive the radio wave transmitted from the transmission section and output an electric signal corresponding to the received radio wave; and a connection section adapted to connect a first housing and a second housing of an electronic instrument pivotably around a center axis; the connection section having a radio signal transmission line formed therein by which wireless transmission can be carried out between the transmission section and the reception section.
Claims22
A signal transmission apparatus comprising:
- a first housing configured to accommodate a transmission side section;
- a second housing configured to accommodate a reception side section;
- and
- a connection section configured to connect the first housing and the second housing for pivotal motion around a center of axis of the connection section, wherein the first housing and the second housing are connected to each other for a folding movement by the connection section, wherein the connection section includes a cavity, wherein a waveguide section for performing wireless communication between the transmission side section and the reception side section is disposed in the cavity,
- wherein the waveguide section comprises:
- a first polarizer that protrudes from an inner side face of a first waveguide and terminates in a cavity of the first waveguide, the inner side face of the first waveguide being spaced apart from a tip of the first polarizer;
- a first substrate spaced apart from the first polarizer along a first waveguide axis, the first polarizer in the first waveguide being between a connection and the first substrate,
- wherein a base of the first polarizer is between the inner side face of the first waveguide and the tip of the first polarizer, a sectional shape of the tip of the first polarizer being smaller than a sectional shape of the base of the first polarizer.
