1. A method for forming a beam of an antenna array, the method comprising:
configuring a first region and a second region for beam forming;
calculating a first directivity function corresponding to the first region and a second directivity function corresponding to the second region;
configuring an objective function based on the first directivity function and the second directivity function;
determining a feeding coefficient of the antenna array based on the objective function; and
forming and transmitting a beam based on the determined feeding coefficient.
