This document presents a comprehensive antenna report from Yusheng Communications, focusing on the passive performance of GPS and Bluetooth antennas. The report details debugging results, indicating approximately 7% efficiency for both Arm GPS and Arm BT antennas. It includes GPS and BT passive graphics, showcasing SWR and Smith chart data.
The report further provides antenna efficiency parameters, listing frequency points, efficiency percentages, efficiency in dB, and gain in dBi for both GPS and BT antennas. Radiation patterns are visualized through 1575MHz passive direction diagrams, offering insights into field pattern characteristics. The document also features motherboard matching details, illustrating the antenna placement within the device. Finally, the antenna test environment is documented, providing context for the reported performance metrics.
