Triple-Band GNSS Patch Antenna GNSSL125182530S
GNSSL125182530S Compact Tri-Band GNSS Active Patch Antenna
The GNSSL125182530S active GNSS internal antenna from YAGEO Group is a compact, high-performance solution designed for space-constrained devices requiring tri-band L1/L2/L5 GNSS support. Featuring a stacked ceramic patch architecture and integrated 30 dB low-noise amplifier, this antenna delivers reliable multi-band performance while minimizing PCB footprint. Strong internal filtering and high out-of-band rejection help improve RF coexistence with nearby LTE, 5G, and Wi-Fi radios, supporting stable operation in dense RF environments.
Engineered for reliable embedded operation, the GNSSL125182530S includes internal ESD protection, an integrated LDO regulator, and a wide operating voltage range of 2.5 to 18 VDC with a maximum current consumption of 16 mA. Its 25 × 25 mm footprint offers a meaningful size reduction compared to traditional tri-band GNSS patch antennas, making it well suited for compact tracking, navigation, and industrial positioning platforms without compromising GNSS performance.
