Beam direction adjustment method, apparatus, and antenna system

Abeam direction adjustment apparatus comprising a memory and at least one processor, wherein the memory stores executable instructions that when executed by the at least one processor, cause the apparatus to perform operations comprising:

• obtaining at least one of an azimuth or a pitch angle of a microwave antenna in an antenna system, wherein the antenna system comprises the microwave antenna and a radome installed at an air interface of the microwave antenna, the radome comprises a liquid crystal array including M×N liquid crystal cells, and both M and N are integers greater than 0;
• determining a target scanning angle of the microwave antenna based on at least one of the azimuth or the pitch angle of the microwave antenna,
• determining a first bias voltage value of the liquid crystal array based on the target scanning angle;
• and
• setting a voltage of the liquid crystal array to the first bias voltage value.

A non-transitory computer-readable storage medium, comprising computer program instructions executable by a computer system to perform operations comprising:

• obtaining at least one of an azimuth or a pitch angle of a microwave antenna in an antenna system, wherein the antenna system comprises the microwave antenna and a radome installed at an air interface of the microwave antenna, the radome comprises a liquid crystal array including M×N liquid crystal cells, and both M and N are integers greater than 0;
• determining a target scanning angle of the microwave antenna based on at least one of the azimuth or the pitch angle of the microwave antenna,
• determining a first bias voltage value of the liquid crystal array based on the target scanning angle;
• and
• setting a voltage of the liquid crystal array to the first bias voltage value.
