ANT-GNFPC-SHL1550M4

Antennas RF Overview

The ANT-GNFPC-SHL1550M4 is a dual-band Flexible Printed Circuit (FPC) antenna designed for Global Navigation Satellite Systems (GNSS). It supports L1/E1/B1 and L5/E5B frequency bands, covering GPS, Galileo, BeiDou, NavIC, and QZSS. The component features a square form factor of 25.0 mm x 25.0 mm with a maximum height of 0.1 mm. It utilizes an MHF4 connector for radio interface and employs permanent adhesive mounting. Key electrical parameters include a peak gain of 3.0 dBi at the L5 band (1.598 GHz to 1.606 MHz) with a VSWR of ≤1.4, and -0.2 dBi gain at the L1 band (1.164 GHz to 1.189 MHz) with a VSWR of ≤2.4.

Antennas RF Feature Summary

• Dual-band operation supporting both L1/E1/B1 and L5/E5B GNSS frequencies for multi-constellation compatibility.
• Ground plane-independent dipole design enabling flexible integration into RF-transparent enclosures.
• Ultra-low profile construction with adhesive backing for secure attachment to non-metallic surfaces.

Antennas RF Applications

• Multi-constellation GNSS receivers requiring precise navigation in challenging urban environments.
• Drones and multi-rotor aerial vehicles.
• Industrial and agricultural robotics.
• Robot lawn mowers and autonomous mobile robots.

Antennas RF Procurement Notes

Verify that the target application requires dual-band L1/L5 support, as this model differs from single-band variants within the same series. Confirm the host device utilizes an MHF4 connector interface, as other models in the family may use MHF1/U.FL connectors. Ensure the installation surface is non-metallic and compatible with the specified adhesive type for proper environmental sealing and signal integrity.

Antennas RF Selection Notes

Select this specific part number when the design mandates an MHF4 connector interface combined with dual-band L1/L5 performance. This model is distinct from the SHL1550UF variant, which uses an MHF1/U.FL connector. Choose this component for applications demanding high precision in obstructed environments where multi-constellation support improves reliability and reduces signal interruption.

Antennas RF Part Context

This component belongs to the ANT-GNFPC-SHL15 series of FPC antennas manufactured by TE Connectivity Linx Technologies. The series provides embedded or internal antenna solutions specifically engineered for GNSS applications. These antennas are characterized by their flexibility and ability to be mounted directly onto plastic or RF-transparent housings, facilitating robust environmental protection without compromising signal reception.

Antennas RF Replacement Considerations

Public confirmed substitute: ANT-GNFPC-SHL1550UF. Note that this alternative utilizes an MHF1/U.FL connector instead of the MHF4 interface found in the primary model. Verify connector compatibility before substitution.
