GGBLA.125.A – GPS L1/L2/L5/L6, GLONASS, BeiDou Ceramic Loop Antenna

GPS L1, L2, L5 and L6 Embedded Ceramic Loop Antenna

The Taoglas GBBLA.125.A is a unique embedded ceramic miniature loop antenna designed for centimetre-level accuracy with RTK systems using the GPS L1/L2/L5/L6 bands. It also covers all other GNSS systems including GLONASS, Galileo, BeiDou and QZSS.

With dimensions of just 10×3.2×1.5mm, a keep-out area of just 15 x 9.8mm on the PCB, the GGBLA.125 makes an ideal multi-band GNSS antenna solution for compact high precision automotive navigation or asset tracking devices where board space is at a premium. An SMD component, delivered on tape and reel, the middle edge-of-board mounted antenna, has an omnidirectional radiation pattern that allows customers to use an omnidirectional antenna in devices where the orientation of the product may be unknown, or subject to frequent movement.

The wide bandwidth maintains high efficiency and reception stability on all GNSS bands from 1164MHz to 1602MHz. The GGBLA.125 exhibits efficiencies of between 60% and 80%, depending on the band used. With a peak gain of 2.6-3.6dBi, the gain performance compares with the ranges of much larger patch antennas of up to 18 x 18mm. Based on the loop antenna electrical effect, this antenna works best when placed in the centre of the edge of the board.

Typical Applications Include:
  • Navigation & RTK Systems
  • Transportation, Marine & Agriculture
  • Autonomous Vehicles
  • UAVs and Robotics
  • IoT Devices
  • Location-based applications

As with all onboard SMD antennas, care must be taken to ensure the device ground-plane layout and antenna matching has been done correctly. At any of our global design and test facilities, Taoglas can offer professional Gerber review, transmission line design, general integration support and final matching services of the GGBLA.125.A on your device board.
