Page 3-4 of 12 2.2.2 Efficiency and Gain The gain of the antenna was measured in OPO’s 3D anechoic chamber in Shenzhen, China. The chamber is a ETS system capable of doing tests from 380MHz to 6GHz. Coaxial chokes on the feed cable were used to mitigate surface currents during passive tests. The measurement results are calibrated using dipole standards. For TRP and TIS the chamber uses a 8960 / MT8820C to establish the connection with the mobile device and read the power. 3 Reference measurement data 3.1 Passive Project:D99B Author: Haiou.Zhu File Name: D99B_APP_A.doc Date: 2022-10-25 Revision: A CONFIDENTIAL Shenzhen OnePlusOne Wireless Communication Technology Co.,Ltd.
