Abstract

The invention provides a phase shifter and a phased array antenna, belonging to the technical field of communication. The phase shifter of the present invention includes: a substrate, a signal transmission unit, a phase adjustment unit, at least one semiconductor unit arranged between the signal transmission unit and the phase adjustment unit, at least one semiconductor unit arranged at the phase adjustment unit The first insulating layer between the semiconductor unit and at least one first bias line configured to be electrically connected to the phase adjustment unit. Wherein, the orthographic projection of the first insulating layer on the substrate is not smaller than the overlapping area of ​​the orthographic projection of the phase adjustment unit and the semiconductor unit on the substrate. In the phase shifter provided by the present invention, the semiconductor unit is configured to adjust the phase of the microwave signal according to the bias voltage applied between the signal transmission unit and the phase adjustment unit.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a phase shifter and a phased array antenna. Background technique [0002] Phase shifters can change the phase of electromagnetic wave signals and are widely used in radar, satellite communication, mobile communication and other fields. In the phased array antenna, the phase shifter is used to control the phase of each signal in the antenna array, which can make the radiation beam conduct electrical scanning, and is an important component of the phased array antenna. An ideal phase shifter should have less loss and almost the same loss in different phase states. In addition, an ideal phase shifter should also meet the requirements of fast phase shifting speed and low control power. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems in the prior art, and provides a phase shifter and a phased array antenna with fas...
