Taoglas® announced the GVLB208 Series, an active and passive dual-band GNSS L1/L5 stacked patch antenna and the first products in a new family of ultra-compact antennas. Combining one of the smallest packages available on the market with concurrent L1/L5 support and stable right-hand circular polarization (RHCP), they deliver reliable centimeter-level positioning in a compact 20 x 20 x 8 mm footprint.
The GVLB208 Series is designed for applications that require high-precision positioning in a compact form factor. Its ultra-compact size, dual-band support and circular polarization make it well-suited to designers looking to improve positioning performance without increasing device footprint.
The new antennas address this challenge with 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 an ultra-compact 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 percent 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 major global 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 easily 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 well-suited for autonomous delivery robots requiring seamless sidewalk navigation and precise drop-offs, where every centimeter counts. It also supports applications including unmanned aerial vehicles, telematics systems, fleet and asset tracking, precision agriculture and industrial IoT deployments.
“Dual-band GNSS is becoming the baseline for high-precision positioning, but it often comes with added size and design complexity,” said David Connolly, Global Product Management director at Taoglas. “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, helping designers achieve more reliable positioning accuracy without redesigning their RF layout or increasing device size.”
Taoglas plans to expand the GVLB208 family later this year with an active SMD variant with integrated active electronic components, designed for automated high volume manufacturing.
The GVLB208 Series is available now from Taoglas and its authorized distributors.
