We test the antenna with the latest version handset. And it seems to be acceptable. 2 General Description 2.1 Components/Part revisions VSWR: Voltage Standing Wave Rate. 3 Mechanical Description 4 Electrical Performance 4.1 Set-up 4.1.1VSWR VSWR measurements (S11) were performed using anAgilent 8753D NetworkAnalyzer and the previously described test fixture. Coaxial chokes were used to mitigate surface currents on the outside of the cabling. The testing was performed in free space. 4.1.2 Gain & Radiation Patterns The gain of the antenna was measured in the Lxc’s anechoic chamber. Coaxial chokes on the feed cable were used to mitigate surface currents. The chamber provides less than – 30 dB reflectivity from 300 MHz through 6 GHz and an 18” diameter spherical quite zone. The measurement results are calibrated using both dipole and leaky wave horn standards. 4.1.3 Matching Circuit Description No changed.. DateRevisionDescription of Changes 2022-11-10 RA Measured with 2.4GHz/5.8GHZ antenna sample. Shenzhen Yangyue Electronic Communication Technology Co., Ltd 地址:东莞市虎门镇大宁社区浦江路2号创富赢家产业园A栋6楼 - 4 - 5.
