Taoglas has introduced the GVLB208 Series, a dual-band L1/L5 stacked patch antenna in a 20 x 20 x 8 mm footprint — one of the smallest packages available for concurrent L1/L5 operation. The series is the first in a new family of ultra-compact GNSS antennas from the company.
The single-feed stacked patch design supports simultaneous L1 and L5 reception without the complexity of multi-feed architectures. Dual-band operation reduces multipath interference, improving positioning reliability in complex RF environments. 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, providing stable right-hand circular polarization and consistent positioning performance. It is optimized for GPS, Galileo, GLONASS, and BeiDou.
Two variants are available. The passive GVLB208.A uses a pin-mount configuration compatible with standard PCB designs, with optimal performance on a 70 x 70 mm ground plane. The active AGVLB208.A adds onboard electronics and filtering and ships with a 1.13 mm micro-coax cable and I-PEX MHF I connector for direct integration with current multiband GNSS modules.
Target applications include UAVs, autonomous delivery robots, telematics, and fleet management — use cases where high-precision positioning is required but form factor constraints limit antenna options.
