The present application discloses a signal converter and a microstrip-waveguide signal conversion device. The signal converter includes: a dielectric substrate, a signal transmission structure, and the signal transmission structure includes a transmission microstrip line and a balanced-unbalanced conversion device, differential microstrip line and impedance converter; the balanced-unbalanced converter connects the microstrip line and the differential microstrip line, and the balanced-unbalanced converter is used to delay the transmission microstrip line signal phase; one end of the impedance transformer is connected to the differential microstrip line, and the impedance transformer is used to better propagate the differential signal from the transmission microstrip line and the balun to the The broadband feed source; the broadband feed source is connected to the end of the impedance converter away from the microstrip line, and the broadband feed source is used to radiate the electromagnetic field signal to space by using the differential signal in the form of radio frequency current. The signal converter can reduce insertion loss.
Description
technical field [0001] The present application relates to the technical field of signal transmission, and in particular, to a signal converter and a microstrip line-waveguide signal conversion device. Background technique [0002] With the rapid development of intelligent vehicle technology, the requirements for the application technology of automotive millimeter-wave radar are getting higher and higher, especially the 4D imaging millimeter-wave radar technology, which can assist the detection of the surrounding environment during the driving process of the car. The development of autonomous driving is crucial. [0003] Traditional radar antennas have the disadvantages of narrow bandwidth, large standing waves, low efficiency, and high cost of high-frequency circuit boards, which cannot meet the needs of automobiles for autonomous driving. The radar antenna is connected to the waveguide antenna through a microstrip-waveguide converter. The traditional microstrip line wavegu...
