The 3D Far-Field Antenna Measurement Technology for Radiation Efficiency, Mean Effective Gain and Diversity Antenna Operation

In this paper, facilities of antenna measurement have recently commissioned a spherical far-field measurement system. The low profile far-field spherical scan system provides significant advantages over the older far-field testing including elimination of problem of simple theta (θ) and phi (ø) rotary axis with indoor far-field range testing, complete measurement characterization of the antenna, and improved accuracy. The mobile phone under test of far-field range testing has been the plan at the Cellular Telecommunications & Internet Association (CTIA) [1] certification program test requirements for performing radiated power and receiver performance measurement. This paper will discuss the antenna and wireless system integration tested with the TRP/TIS and spherical antenna measurement for far-field system. The spherical far-field antenna system applied to total radiation efficiency, mean effective gain (EMG) and diversity gain measurement and applications.
