Provided are a phase shifter, a preparation method thereof, and an antenna. The phase shifter includes at least one phase shifting unit, and the phase shifting unit includes a microstrip line, a photo-dielectric layer, a ground electrode, and at least one light guiding structure; the microstrip line is located on a side of the photo-dielectric layer, and the ground electrode is located on a side of the photo-dielectric layer facing away from the microstrip line; the light-guiding structure at least partially overlaps the photo-dielectric layer, and the light-guiding structure is configured to guide light into the photo-dielectric layer.

Antenna including at least one microstrip line phase shifting unit having a photo-dielectric layer and a light guiding structure configured to guide light into the photo-dielectric layer

Provided are an antenna and a preparation method thereof, a phase shifter, and a communication device. The antenna includes a first electrode, a second electrode, a third electrode, and a photodielectric variable layer. The first electrode and the second electrode are respectively disposed on opposite two sides of the photodielectric variable layer. The first electrode includes a plurality of transmission electrodes, and the plurality of transmission electrodes are configured to transmit an electrical signal. The second electrode is provided with a fixed potential. The third electrode includes a plurality of radiator units, and the plurality of radiator units are configured to send the electrical signal. The antenna further includes at least one light-emitting element configured to emit light irradiated to the photodielectric variable layer to change a dielectric constant of the photodielectric variable layer.

Antenna and preparation method thereof, phase shifter and communication device

A scanning antenna is provided in the present disclosure. The scanning antenna includes a first substrate and a second substrate which are arranged oppositely; a liquid crystal layer between the first substrate and the second substrate; and a feed signal access terminal and a plurality of phase shift units, where the plurality of phase shift units is connected with each other, each phase shift unit is connected to the feed signal access terminal, and electrical lengths between at least two phase shift units and the feed signal access terminal are different. The present disclosure not only realizes one-dimensional wave beam scanning, but also has desirable scanning effect. The bias voltage is not needed to be independently applied to each phase shift unit, which can greatly simplify the bias voltage line configuration and be beneficial for reducing production cost and wiring difficulty.
