ANT-4FP2906-UFL

Antennas RF Overview

The ANT-4FP2906-UFL is a compact helical PCB antenna designed for operation at 433 MHz. It features a vertical radiation pattern with a gain of 1 dBi and utilizes an adhesive mounting method for secure installation. The component includes a U.FL connector interface, facilitating easy integration into RF circuits without requiring additional tuning. With a physical length of 29 mm, it serves as a ready-to-operate solution for ISM band applications.

Antennas RF Feature Summary

• Compact helical design optimized for space-constrained environments
• Integrated adhesive backing for direct surface mounting
• Pre-tuned operation eliminating the need for circuit adjustment
• Vertical polarization suitable for standard telemetry links

Antennas RF Applications

• ISM band telemetry systems
• Wireless sensor networks
• Remote control devices
• IoT data transmission modules

Antennas RF Procurement Notes

Verify that the U.FL connector variant matches the host board footprint. Confirm the adhesive type compatibility with the target enclosure material to ensure long-term mechanical stability. Check RoHS compliance status against specific regulatory requirements for the destination market before finalizing orders.

Antennas RF Selection Notes

Choose this model when a low-profile, vertically polarized antenna is required for 433 MHz ISM band operations. The integrated adhesive simplifies assembly compared to screw-mount alternatives. Ensure sufficient clearance around the antenna element to maintain the specified 1 dBi gain and radiation pattern integrity.

Antennas RF Part Context

This component belongs to the ANT-4FP2906 series from RF Solutions, which offers flexible PCB antenna solutions. The series provides both solder-in and connectorized versions to accommodate different manufacturing processes. The helical structure allows for reduced height while maintaining efficient radiation characteristics in the sub-GHz frequency range.

Antennas RF Replacement Considerations

Direct substitutes within the same series include variants with different connector types or mounting styles. Verify that any replacement maintains the 433 MHz center frequency and 1 dBi gain specifications. Ensure mechanical dimensions and connector interfaces are compatible with existing board layouts.
