This document presents a comprehensive antenna testing report conducted by Fbetter for TWS earbuds, specifically model C109. The report details various tests and measurements performed in our state-of-the-art OTA lab, including OTA (Over-the-Air) performance in both free space and head model scenarios. The lab is equipped with a 5m*3m*3m single probe head, covering a frequency range of 400MHz-6GHz, and supports various wireless technologies such as GSM, CDMA, WCDMA, TD, LTE, BT, WIFI, GPS, and NB-IOT.
The report includes detailed analysis of antenna efficiency, impedance, and return loss. It also presents data on both passive and active antenna performance, including TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity) measurements. The testing was conducted using FPC/steel sheet materials, and the performance was evaluated based on customer experience and chamber data. The report aims to provide a thorough understanding of the antenna characteristics of the TWS earbuds, model C109.
