Overview
The Quectel YFGC018WWDM is a high-performance, passive embedded GNSS antenna designed for SMT (surface mount) assembly. Housed in a compact ceramic package measuring 18mm × 18mm × 2mm, this antenna supports the L1 frequency band (1559–1606MHz), covering GPS L1, GLONASS G1, Galileo E1, BDS B1I/B1C, QZSS L1, and other compatible GNSS signals.
Key electrical characteristics (tested on a 50mm × 50mm reference PCB at 1575MHz):
- VSWR: 1.26
- Return loss: -18.8dB
- Efficiency: up to 43.2%
- Peak gain: 0.11dBi
- Axial ratio: 0.97dB (circular polarization, RHCP)
The antenna features a directional radiation pattern with right‑hand circular polarization (RHCP). It is RoHS and REACH compliant, operates from -40°C to +85°C, and withstands peak reflow temperatures of 260°C for 5 seconds. The datasheet provides detailed S‑parameters, radiation performance (efficiency, gain, axial ratio, 2D/3D patterns), PCB footprint recommendation, and a reflow soldering profile
