Taoglas has introduced the GVLB208 series, a dual-band L1/L5 GNSS stacked patch antenna family in a 20 mm x 20 mm x 8 mm footprint. The series is available in passive (GVLB208.A) and active (AGVLB208.A) configurations, both using a single-feed architecture that supports concurrent L1 and L5 reception without the complexity of multi-feed designs.
The antenna delivers peak gain of up to 1.5 dBi, approximately 50% efficiency across both bands, and an axial ratio of around 4 dB, with stable right-hand circular polarization. It supports GPS, Galileo, GLONASS and BeiDou. The passive variant uses a pin-mount configuration optimized for a standard 70 mm x 70 mm ground plane. The active AGVLB208.A ships with 1.13 mm micro-coax cable and an I-PEX MHF I connector.
Target applications include UAVs, autonomous delivery robots, precision agriculture, telematics and fleet tracking. Taoglas says dual-band operation reduces multipath interference for more reliable centimeter-level positioning in complex RF environments.
An active SMD variant with integrated electronics designed for high-volume automated manufacturing is planned for later this year. The GVLB208 series is available now through Taoglas and its authorized distributors.
