Dongguan Teconn Electronics Technology Co., Ltd. Revision History Date 2019-07-8 Revision RA Description of Changes Measured with 2.4GHz Antenna sample. Technical Summary This report summarizes the electrical results of the proposed antenna to support the 2.4GHz Antenna program. We test the antenna with the latest version handset. And it seems to be acceptable. General Description 2.1 Components/Part revisions VSWR: Voltage Standing Wave Rate. Mechanical Description Electrical Performance 4.1 Set-up 4.1.1 VSWR VSWR measurements (S11) were performed using an Agilent 8753D Network Analyzer 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 HTs 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 3 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.. DongguanTeconnElectronicsTechnologyCo.,Ltd.
