Abstract: An antenna apparatus, which includes an antenna array and a processor, where the processor is configured to determine a first antenna subarray from N rows and M columns of radiating elements of the antenna array, where the first antenna subarray includes X1 rows and Y1 columns of radiating elements, and X1 is greater than Y1, control a phase shift increment change of the first antenna subarray to generate a plurality of first beams, determine a first aligned beam from the first beams based on a first feedback from a receive end, determine a second antenna subarray, where the second antenna subarray includes X2 rows and Y2 columns of radiating elements, and Y2 is greater than X2, and determine a second aligned beam from the second beams based on a second feedback from the receive end.
