phase change dielectric unit, dielectric phaser and base station antenna

摘要

The present invention relates to the field of communication technology and in particular to technology related to impedance matching in communication technology and in particular to a phase shift dielectric unit, dielectric phaser and base station antenna. it includes a supply network and a dielectric plate for impedance matching and for moving along a predetermined path, a dielectric impedance matching portion that is disposed at one end of the dielectric plate adjacent an input port in the power network. The present invention not only reduces the number of impedance matching and network loss, but also reduces the equivalent electrical length of the entire network, saves costs effectively, reduces the complexity of disassembly and assembly of related components, and improves disassembly efficiency. it's Photoshop. In addition, it is convenient to install as many phase change dielectric units as possible in a limited space in the cavity and to ensure an equal phase relationship between the output ports, thereby improving the performance of the dielectric phaser and the station antenna. Electric adjustable base.
