Test methodologies for Active Antenna System

Abstract

Test methods for Active Antenna System (AAS) have been a hot topic in 3Gpp. Conductive and Over-The-Air (OTA) test approaches are two main candidate methods. In this paper, the structure for Active-Antenna-System is introduced and the advantages and disadvantages between the two test methodologies are discussed. Consequently, the balance between efficiency and accuracy may be delicate.
