The YFGC009WWD is a high-performance, passive GNSS patch antenna designed for surface-mount (SMT) assembly. Housed in a compact 25 x 25 x 4 mm ceramic package, this antenna covers the full GNSS frequency band from 1559 MHz to 1606 MHz, supporting GPS, GLONASS, Galileo, BDS, QZSS, and IRNSS L1/L5/E1/B1 applications.
Key electrical and radiation characteristics (tested on a 70 x 70mm reference PCB) include:
- VSWR: 1.27 @ 1575 MHz (GPS L1) | 1.29 @ 1602 MHz (GLONASS G1)
- Return loss: -18.3 dB @ 1575 MHz | -17.8 dB @ 1602 MHz
- Efficiency: up to 79.2 %
- Peak gain: 4.73 dBi @ 1575 MHz | 5.32 dBi @ 1602 MHz
- Polarization: right-hand circular polarization (RHCP)
- Radiation pattern: directional
- Impedance: 50 Ω
