Abstract: The present disclosure provides a phase shifter and an antenna, and relates to the field of communication technology. The phase shifter provided by the embodiment of the present disclosure is divided into a first feeding region, a second feeding region and a phase-shift region. The phase shifter includes: a first substrate and a second substrate provided opposite to each other, a dielectric layer provided between the first substrate and the second substrate, and a first feeding structure and a second feeding structure. The first feeding structure is electrically coupled to one end of the signal line, and the second feeding structure is electrically coupled to the other end of the signal line. The first feeding structure is located in the first feeding region; and the second feeding structure is located in the second feeding region. Recesses are formed in the first base substrate and/or in the second base substrate.
