JLT868S25P4X

Antennas RF Overview

The JLT868S25P4X is a UHF ceramic patch antenna manufactured by JC Antenna. It operates within the 865MHz to 871MHz frequency band, with a specified center frequency of 868±3.0 MHz. The component features right-hand circular polarization (RHCP) and requires a ground plane measuring 70x70 mm for optimal performance. Electrical specifications include a return loss at the center frequency of ≥15dB. The physical dimensions are limited to a maximum height of 0.157 inches (4.00mm).

Antennas RF Feature Summary

• Utilizes ceramic patch construction for compact integration.
• Supports right-hand circular polarization for signal stability.
• Designed for specific UHF band operation.

Antennas RF Applications

• UHF communication systems
• IoT device connectivity
• RFID infrastructure

Antennas RF Procurement Notes

Verify the required ground plane size of 70x70 mm during system design, as this antenna specification depends on it. Confirm that the application environment supports the RHCP requirement. Ensure the operating frequency aligns with the 865MHz to 871MHz range. Check local regulatory compliance for the UHF band usage in the target deployment region before finalizing procurement.

Antennas RF Selection Notes

Select this model when a low-profile UHF solution with circular polarization is required. The 4.00mm height makes it suitable for space-constrained designs. Consider the mandatory 70x70mm ground plane constraint during PCB layout. This part is appropriate for applications needing stable reception in the 868MHz ISM band without complex matching networks.

Antennas RF Part Context

JC Antenna manufactures various RF components including GPS, GLONASS, and BEIDOU antennas. The JLT868S25P4X belongs to their UHF patch antenna series, distinct from their GNSS or cellular solutions. The company provides custom antenna solutions for IoT and communication sectors, positioning this model as a specialized component for specific frequency bands rather than a universal broadband device.
