An active and passive dual-band GNSS L1/L5 stacked patch antenna in a 20x20x8mm package

It claims to have one of the smallest packages available on the market which is combined with concurrent L1/L5 support and stable right-hand circular polarization (RHCP) to deliver  centimetre -level positioning in a  20 x 20 x 8 mm footprint.

The devices target application of high-precision positioning in a compact form factor is supplied by a single-feed stacked patch design that supports concurrent L1 and L5 GNSS bands. By leveraging dual-band operation, they significantly reduce the impact of multipath interference, enabling more reliable positioning and improved accuracy in complex RF environments.

Designed around a 20 x 20 x 8 mm ceramic form factor, the series delivers dual-band L1/L5 performance typically associated with larger GNSS patch antennas, without increasing device footprint.

The antenna achieves peak gain of up to 1.5 dBi, approximately 50% efficiency across both bands, and an axial ratio of around 4 dB, supporting stable right-hand circularly polarized (RHCP) signal reception and consistent positioning performance.

Optimized for GNSS constellations, including GPS, Galileo, GLONASS and BeiDou, the GVLB208 Series supports reliable operation across varied RF environments.

The passive GVLB208 A single-feed architecture enables dual-band L1/L5 performance without the complexity of multi-feed designs, while its pin-mount configuration simplifies RF layout and integration.

It can be implemented on standard PCB designs, with optimal performance achieved on a typical 70 x 70 mm ground plane.

The active AGVLB208.A, including active electronics and filters, is supplied with 1.13 micro-coax cable and an I-PEX MHF I connector for effortless integration with the latest multiband GNSS modules.

The GVLB208 Series is particularly suitable for autonomous delivery robots requiring seamless sidewalk navigation and precise drop-offs, where every centimeter counts. It also supports applications including unmanned aerial vehicles (UAVs), telematics systems, fleet and asset tracking, precision agriculture, and industrial IoT deployments.

“What differentiates the GVLB208.A and the wider series is the ability to deliver L1 and L5 performance in a really compact, single-feed architecture,” says Taoglas’ David Connolly.
