This document presents a detailed overview of the antenna evaluation performance for Project QDM083-EA. The report encompasses various aspects, starting with the project's fundamental details, including the project name, device dimensions (142mm*110mm*36mm), and mainboard dimensions (125mm*70mm*1.6mm). The device features four antennas, each designed for specific network types and frequency bands.
The antenna network supports a wide range of communication standards, including LTE/NTN, operating within the 698-960MHz and 1710-2690MHz bands, as well as S-band (1518-1675MHz) and L-band (1980-2200MHz). Additional support is provided for SUB-GHz (868-924MHz), GNSS (1575.42MHz), and WIFI/BLE (2400-2500MHz) technologies. The document further details the antenna placement within the device, providing a visual representation of the LTE, WiFi, sub-G, and GNSS antenna locations.
The report includes comprehensive antenna performance data, including VSWR and S11 measurements, efficiency and gain figures across various frequencies, and radiation patterns for the LTE antenna at different frequency points. OTA test data for the LTE antenna is also presented, providing insights into the antenna's performance in real-world conditions.
