Title:

OPTIMIZATION METHOD AND APPARATUS FOR EFFICIENT BEAM SYNTHESIS

Document Type and Number:

WIPO Patent Application WO/2021/107299

Kind Code:

A1

Abstract:

Disclosed are a communication technique which merges, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. A beam forming method for an array antenna, according to one embodiment of the present disclosure, can comprise the steps of: setting a first area and a second area for beam formation; calculating a first directivity function corresponding to the first area and a second directivity function corresponding to the second area; setting an objective function on the basis of the first directivity function and the second directivity function; determining a feed coefficient of the array antenna on the basis of the objective function; and forming a beam on the basis of the determined feed coefficient.
