摘要： The present invention provides a coax-waveguide adapter, which improves in-band flatness of a reflection coefficient in a simple way. The coax-waveguide adapter includes: a cavity-shaped waveguide connection component, a coaxial external conductor connected to the cavity-shaped waveguide connection component, and a coaxial internal conductor that is disposed inside the coaxial external conductor along an axial direction of the coaxial external conductor and inserted into the cavity-shaped waveguide connection component, where the coax-waveguide adapter further includes: an electromagnetic parameter adjusting component that is disposed inside a cavity of the cavity-shaped waveguide connection component and used for reducing an effective dielectric constant and an effective magnetic conductivity of the coax-waveguide adapter. According to the coax-waveguide adapter provided in the present invention, an external geometrical shape and geometrical dimension of the coax-waveguide adapter are not changed, an implementation manner is simple and easy, costs are low, but in-band flatness of a reflection coefficient can be effectively improved.

摘要： Embodiments of the present invention provide a phased array system and a beam scanning method. The phased array system includes at least two traveling wave antennas (21) arranged in parallel, and each traveling wave antenna (21) includes at least two antenna units (22) sequentially connected; and a first end (23) of each traveling wave antenna (21) connects to a corresponding first radio frequency channel (20), the first end (23) of each traveling wave antenna (21) connects to a signal processing module (24) of the phased array system by using the corresponding first radio frequency channel (20), and a phase and/or an amplitude of a signal inputted by the signal processing module (24) from the first end (23) into the traveling wave antenna (21) may be adjusted by adjusting a configuration of the first radio frequency channel (20). According to the phased array system and the beam scanning method, based on implementation of spatial beam scanning, a requirement for a quantity of radio frequency channels is reduced, and therefore complexity and costs of the phased array system are reduced.
