Abstract

The embodiment of the invention provides a phased-array antenna and a control method thereof, relates to the technical field of electromagnetic waves, and reduces the cost of the phased-array antenna. The phased-array antenna comprises a first substrate and a second substrate, a cavity is formed between the first substrate and the second substrate, and the cavity comprises a plurality of phase shifting units. Each phase shifting unit comprises a feed part which is arranged on the surface, far away from the second substrate, of the first substrate and connected with a radio frequency signal end, a radiator which is arranged on the surface, far away from the second substrate, of the first substrate and is insulated from the feed part, a grounding electrode which is arranged on the surface, facing the second substrate, of the first substrate and connected with a grounding signal end, is overlapped with the feed part and the radiator, is provided with a first opening located in the area overlapped with the feed part and a second opening located in the area overlapped with the radiator, and a transmission electrode which is arranged on the surface, facing the first substrate, of the second substrate and connected with a control signal line, is overlapped with the feed part, the radiator and the grounding electrode, and overs the first opening and the second opening.

Description

【Technical field】 [0001] The invention relates to the technical field of electromagnetic waves, in particular to a phased array antenna and a control method thereof. 【Background technique】 [0002] With the gradual evolution of communication systems, phased array antennas have been widely used. In the prior art, a phased array antenna includes a plurality of antenna units, and the antenna units are used for The radio frequency signal is radiated, and after the radio frequency signals radiated by multiple antenna units interfere with each other, a beam with a main lobe direction is formed. Since the existing phase shifter is a fixed phase shifting device, if each antenna unit includes only one phase shifter, one antenna unit can only radiate radio frequency signals of one phase. After interference, the antenna can only form a beam with a specific main lobe direction, and the main lobe direction of the beam cannot be adjusted. Therefore, each antenna unit currently correspond...
