Taoglas has introduced the GVLB208 Series, an active and passive dual-band GNSS antenna family for compact L1/L5 positioning designs.
The series uses a stacked ceramic patch in a 20x20x8 mm footprint and supports concurrent L1 and L5 operation. Taoglas says the design is intended for systems that need higher positioning accuracy but cannot accommodate the larger patch antennas usually associated with dual-band GNSS reception.
The GVLB208 Series uses a single-feed stacked patch architecture. That matters because multi-feed patch designs can add RF layout and integration complexity, particularly in compact host systems where the antenna, ground plane, receiver and other radios are all fighting for space.
The passive GVLB208.A is a pin-mount antenna for integration on standard PCB designs. Taoglas specifies optimal performance on a typical 70 x 70 mm ground plane. The company lists the passive antenna with RHCP polarisation, L1/L5 coverage, 50 Ω impedance, a -40 °C to 85 °C operating range, 16 g weight and maximum gain of 1.5 dBi.
The active AGVLB208.A adds active electronics and filtering, and is supplied with a 1.13 mm micro-coaxial cable and I-PEX MHF I connector. That version is aimed at direct integration with current multiband GNSS modules where designers want an active antenna path without adding separate front-end circuitry.
By supporting both L1 and L5 bands, the dual-band GNSS antenna is intended to reduce the effect of multipath interference and improve reliability in difficult RF environments. Taoglas quotes peak gain of up to 1.5 dBi, around 50% efficiency across both bands, and an axial ratio of about 4 dB.
The antennas are optimised for major GNSS constellations including GPS, Galileo, GLONASS and BeiDou. The target applications include UAVs, autonomous delivery robots, telematics systems, fleet and asset tracking, precision agriculture and industrial IoT deployments.
For eeNews Europe readers, the launch follows earlier coverage of Taoglas work on compact RF integration, including Taoglas antennas for compact IoT designs combining cellular, GNSS and Wi-Fi connectivity.
Taoglas says the GVLB208 Series is available now from the company and its authorised distributors. The company also plans to expand the family later in 2026 with an active SMD variant that integrates active electronic components and is designed for automated high-volume manufacturing.
