    Abstract: The present disclosure provides a phase shifter including: a first substrate and a second substrate. The first substrate includes a reference electrode and a signal electrode, and the signal electrode includes a main structure and multiple branch structures. The second substrate includes multiple patch electrodes, and the multiple patch electrodes are arranged in a one-to-one correspondence with the multiple branch structures to form multiple variable capacitors. The phase shifter has a first region, and a second region and a third region which are respectively provided on two sides of the first region; and for any two of variable capacitors located on a same side of the first region, an overlap area of patch electrode and branch structure of a variable capacitor close to the first region is greater than or equal to that of a variable capacitor away from the first region.

    CPC classification number: H01Q13/106 ,  H01Q1/422

    Abstract: An antenna includes: a dielectric layer; a reference electrode layer on a first surface of the dielectric layer and with a slot therein; radiation structure on a second surface of the dielectric layer. The radiation structure includes a plurality of radiation parts spaced apart from each other, each of which includes radiation elements spaced apart from each other. The plurality of radiation parts in each radiation structure include first radiation part and a second radiation part; and a first microstrip line and a second microstrip line are on the second surface. The first microstrip line is configured to feed power to the radiation elements in the first radiation part, and the second microstrip line is configured to feed power to the radiation elements in the second radiation part. The first microstrip line has a feed direction different from that of the second microstrip line.
