Phase shifter and electronic equipment

The invention provides a phase shifter and electronic equipment, and belongs to the technical field of communication. The phase shifter comprises a first dielectric substrate and a second dielectric substrate which are oppositely arranged, a first conductive pattern and a second conductive pattern which are arranged on one side, close to the second dielectric substrate, of the first dielectric substrate, and a third conductive pattern which is arranged on one side, close to the first dielectric substrate, of the second dielectric substrate, the adjustable dielectric layer is arranged between a layer where the first conductive pattern and the second conductive pattern are located and a layer where the third conductive pattern is located; the third conductive pattern comprises a main body structure, and a first branch and a second branch which are respectively connected to two sides of the extension direction of the main body structure; the phase shifter further comprises a split resonant ring arranged on the side, away from the third conductive pattern, of the second dielectric substrate, and the orthographic projection of the split resonant ring and the orthographic projection of the third conductive pattern on the first dielectric substrate are partially overlapped.
