Abstract: The present disclosure describes a terahertz carrier sending apparatus and a terahertz carrier receiving apparatus. The sending apparatus includes a radio frequency sending chip, a mode conversion structure, a terahertz transmission line, and a circuit board. The radio frequency sending chip is packaged on the circuit board, and includes a radio frequency sending circuit, a feed transmission line, and a mode excitation structure. The mode conversion structure includes a metal inner wall, configured to couple a terahertz signal excited by the mode excitation structure into the terahertz transmission line. The terahertz transmission line is configured to transmit the terahertz signal. The receiving apparatus includes a similar part in a receiving direction. The subject matter herein implements efficient electromagnetic coupling and improves data transmission bandwidth.

Abstract: A distributed radar includes a control unit, a receive antenna, and N transmit antennas. The N transmit antennas include a first transmit antenna, a second transmit antenna, and a third transmit antenna. There is a first distance (Δx1) between the first transmit antenna and the second transmit antenna, there is a second distance (Δx2) between the first transmit antenna (201) and the third transmit antenna (203), and Δx1 is less than Δx2. The second transmit antenna is connected to the control unit by using a first cable (L1), the third transmit antenna is connected to the control unit by using a second cable (L2), a ratio of Δx1 to Δx2 is a first ratio, a ratio of a length of L1 to a length of L2 is a second ratio, and the second ratio is greater than the first ratio.

Abstract: A transmission cable is provided to implement high-speed inter-device interconnection and intercommunication. The transmission cable includes a positive dispersion transmission section, a negative dispersion transmission section, and a dispersion matching section. A cross-sectional diameter of the positive dispersion transmission section is less than a cross-sectional diameter of the negative dispersion transmission section. The dispersion matching section is configured to connect the positive dispersion transmission section and the negative dispersion transmission section. The transmission cable can implement dispersion cancellation to reduce total group delay.
