要約(英語): The 4G system (LTE-Advanced), and the 5G system as the next generation mobile communication are shifting to broadband communication using wider bandwidth for higher data rate than conventional system. For example, carrier aggregation technology is in the 4G, and millimeter wave is planning to be used in the 5G to expand frequency range. Therefore, as the evaluation environment for mobile communication terminal including the antenna performance are needed in the wider bandwidth and the higher frequency range. In this paper, as the receiver evaluation environment, we focused the anechoic chamber which is high convenience and low cost and we describe possibility of applying it to evaluation for mobile terminal in the frequency range from 700 MHz to 3 GHz. First, we clarify issue of current anechoic chamber for the receiver evaluation. And then, from BER characteristic, we show necessary QZ level and miniaturization size of anechoic chamber for the receiver evaluation. As a result, they are obtained that QZ level is -30 dB or less and miniaturization internal size of chamber is Sx=900 mm, Sy=Sz=650 mm by applying horn antenna as source of wave.
