GPSFB356.A

Antennas RF Overview

The Taoglas GPSFB356.A is a high-performance single-feed stacked patch antenna designed for multiband GNSS applications. It supports GPS L1 (1575.42 MHz) and L2 (1227.6 MHz), GLONASS G1 (1602 MHz), and BeiDou B1 (1561 MHz). The unit features a compact ceramic construction with dimensions of 35 mm x 35 mm x 6 mm, tuned specifically for a 70 mm x 70 mm ground plane. Electrical specifications include gains ranging from 3.02 dBic to 3.54 dBic across bands, a 50 Ohm impedance, and VSWR ratios of 2:1 or 4:1. It operates within a temperature range of -40°C to +85°C and utilizes Right-Hand Circular Polarization.

Antennas RF Feature Summary

• Multiband coverage supporting GPS L1/L2, GLONASS G1, and BeiDou B1 frequencies via a single feed architecture.
• High gain stability and radiation pattern consistency on both L1 and L2 bands for improved positioning accuracy.
• Compact 6mm height profile suitable for space-constrained devices requiring precision navigation.

Antennas RF Applications

• High-accuracy positioning and navigation systems
• Unmanned Aerial Vehicles (UAVs)
• Urban area GPS fix reliability enhancement

Antennas RF Procurement Notes

Verify the specific datasheet version when ordering, as performance metrics may vary slightly between revisions. Confirm that the application circuit provides the required 70 mm x 70 mm ground plane size, as the antenna is tuned specifically for this dimension. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain electrical integrity and longevity.

Antennas RF Selection Notes

Select the GPSFB356.A when multi-constellation support including GPS, GLONASS, and BeiDou is required in a low-profile form factor. This model is appropriate for designs prioritizing gain stability over dual-band frequencies. Consider the adhesive mount style and physical footprint constraints during PCB layout. Verify compatibility with the target receiver's impedance matching requirements before finalizing the design.

Antennas RF Part Context

This component belongs to the Taoglas GPSFB series of GNSS antennas. It represents a specialized solution for indoor and outdoor applications requiring precise satellite tracking. The stacked patch technology distinguishes it from standard single-band units by enabling simultaneous reception of multiple frequency bands without additional active components.

Antennas RF Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult manufacturer catalogs for alternative models if specific band coverage or physical dimensions differ from project requirements.
