Description
Embedded ceramic loop antenna designed for multi-band GNSS reception in space-constrained devices, supporting centimetre-level positioning when used within RTK-enabled systems.
- Low-profile, small-footprint SMD/SMT antenna for compact PCB designs
- Multi-band GNSS coverage for robust positioning performance across major constellations
- Omnidirectional radiation pattern to help maintain reception when device orientation is unknown or frequently changing
- Designed for integration on an 80 x 40mm ground plane (recommended) to support optimal performance
Typical use cases include navigation and RTK systems, transportation (including marine and agriculture), autonomous vehicles, UAVs and robotics, IoT devices, and other location-based applications.
Installation / Environmental
Recommends positioning the antenna at the centre of the PCB's longer edge. Please see section 7 of this datasheet for the recommended integration guide.
Recommends using an 80x40mm ground plane for optimal performance. However, Section 10 demonstrates how reducing the ground plane size impacts performance degradation.
Recommends mounting the GGBLA.125 at the centre of the long side of the ground plane to achieve optimal performance. Alternatively, the antenna can be mounted at the corner of the ground plane. Section 11 outlines recommended matching guidelines and evaluates the antenna's performance in a corner-mounted configuration. It also includes a recommended footprint specific to this mounting option, which differs from the standard design.
Section 12 of this document covers tuning for DECT/NTN applications, and how to match to ensuring optimal performance across DECT and NTN frequency bands.
