Dual Band Passive GNSS Antenna
SPATB1L1G1364BL5456_JHS04
SPATB1L1G1364BL5456_JHS04 is a dual-band passive GNSS ceramic patch antenna designed for B1/L1/G1 and L5 signal reception. With a compact stacked patch structure, RHCP polarization, low reflection loss, low axial ratio and high gain performance, it provides reliable GNSS signal reception for multi-frequency navigation systems, receivers, modules and compact positioning terminal devices.
SPATL1364BL5366_J7013 supports GPS L1/L5, GLONASS G1, Galileo E1/E5a, BeiDou B1I/B1C/B2a, QZSS L1/L5 and IRNSS L5, enabling reliable multi-frequency GNSS signal reception for positioning and navigation applications
The antenna adopts a compact stacked ceramic patch structure with upper and lower four-feed-point designs, helping achieve low reflection loss, a low axial ratio and improved phase center stability
With RHCP polarization, 50 Ω impedance, high-band frequency coverage of 1559–1606 MHz and low-band coverage of 1164–1189 MHz, the antenna delivers stable passive GNSS reception without requiring external power
Built with high-Q dielectric ceramic material, a silver-plated electrode and ground base, copper tin-plated pins and an adhesive mounting design, the antenna is suitable for integration into GNSS receivers, modules, IoT terminals and positioning devices
