The GVLB208 series is designed for applications requiring high-precision positioning in a compact form factor. Its ultra-compact size, dual-band compatibility, and circular polarization make it ideal for designers looking to improve positioning performance without increasing device size.
The new antennas address this challenge with a single-feed stacked patch design that supports both GNSS L1 and L5 bands simultaneously. By leveraging dual-band operation, they significantly reduce the impact of multipath interference, enabling more reliable positioning and greater accuracy in complex RF environments.
Designed around an ultra-compact 20 x 20 x 8 mm ceramic form factor, the series delivers L1/L5 dual-band performance typically associated with larger GNSS patch antennas, without increasing the device's size. The antenna achieves a maximum gain of up to 1.5 dBi, approximately 50% efficiency on both bands, and an axial ratio of around 4 dB, enabling stable reception of right-hand circularly polarized (RHCP) signals and consistent positioning performance.
Optimized for the world's major GNSS constellations, including GPS, Galileo, GLONASS, and BeiDou, the GVLB208 series ensures reliable operation in diverse RF environments.
The GVLB208's single-power passive architecture enables dual-band L1/L5 performance without the complexity of multi-power designs, while its pin-mount configuration simplifies RF design and integration. It can be easily implemented on standard PCB layouts, with optimal performance on a typical 70 x 70 mm ground plane.
The active AGVLB208.A, which includes active electronics and filters, is supplied with a 1.13 mm micro-coaxial cable and an I-PEX MHF I connector for effortless integration with the latest multi-band GNSS modules.
The GVLB208 series is especially well-suited for autonomous delivery robots that require smooth sidewalk navigation and precise deliveries, where every inch counts. It also supports applications such as unmanned aerial vehicles (UAVs), telematics systems, fleet and asset tracking, precision agriculture, and industrial IoT deployments.
“Dual-band GNSS is becoming the standard for high-precision positioning, but it often comes with increased size and design complexity,” said David Connolly, global director of product management at Taoglas. “What sets the GVLB208.A apart from the rest of the series is its ability to deliver L1 and L5 performance in a truly compact, single-feed architecture, helping designers achieve more reliable positioning accuracy without having to redesign their RF scheme or increase device size.”.
Taoglas plans to expand the GVLB208 family later this year with an active SMD variant featuring integrated active electronics, designed for high-volume automated manufacturing.
