Abstract:
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.
Abstract:
A phased array system includes at least two traveling wave antennas arranged in parallel, and each traveling wave antenna includes at least two antenna units sequentially connected. A first end of each traveling wave antenna connects to a corresponding first radio frequency channel. The first end of each traveling wave antenna connects to a signal processing module of the phased array system by using the corresponding first radio frequency channel. A phase and/or an amplitude of a signal inputted by the signal processing module from the first end into the traveling wave antenna may be adjusted by adjusting a configuration of the first radio frequency channel.
Abstract:
A method, node device, and system are disclosed for establishing a label switched path, which belong to the field of communications technologies. Establishing the label switched path between a source node and a sink node utilizes a connection establishment request message that carries bandwidth request information corresponding to different conditions. Based on the bandwidth request information corresponding to the different conditions, various amounts of bandwidth resources corresponding to the different conditions are reserved on local links that establish a connection between the source node and the sink node.
