  • Patent number: 10511465
    Abstract: The present technology relates to a transmitter, a transmission method, a receiver, and a reception method that can keep upsizing and cost increase to a minimum. The transmitter and the receiver have a detection mode and a communication mode as operation modes. The detection mode detects contact between a first waveguide on the side of the transmitter and a second waveguide on the side of the receiver. The communication mode sends or receives a modulated signal, acquired through frequency conversion of a baseband signal, via the first and second waveguides. The transmitter sends a given signal to the first waveguide in the detection mode. The transmitter and the receiver go from the detection mode to the communication mode in response to a given signal received by the receiver via the second waveguide and send and receive the modulated signal via the first and second waveguides in the communication mode.

  • Publication number: 20190013563
    Abstract: The present disclosure relates to a connector module, a communication circuit board, and an electronic device that are capable of satisfactorily suppressing the leakage of high-frequency electromagnetic waves. The connector module includes an opening and a conductive spring. The opening accepts the insertion of an end of a waveguide that transmits high-frequency electromagnetic waves. The conductive spring locks the waveguide when the waveguide inserted into the opening is pressed toward one inner side surface of the opening. Further, the conductive spring is disposed in a gap between the opening and the waveguide so as to come into contact with the opening and with the waveguide along a direction in which the waveguide transmits the electromagnetic waves. The present technology is applicable, for example, to an electronic device that establishes communication by using millimeter waves.
