摘要
The present invention relates to the field of communications technologies and discloses a phase shifter and a feed network. The phase shifter includes at least one phase shift component. The phase shift component includes a substrate, a microstrip coupling structure disposed on a first plane of the substrate, a microstrip transmission line connected to and coplanar with the microstrip coupling structure, and a microstrip/coplanar-waveguide coupling structure, where the microstrip/coplanar-waveguide coupling structure includes a microstrip connected to and coplanar with the microstrip transmission line, and a coplanar waveguide disposed opposite to the microstrip on the substrate and coupled with the microstrip. A phase shifter using a microstrip/coplanar-waveguide coupling structure has a small volume and costs low, thereby facilitating feed network design.
