JCG146

Antennas RF Overview

The JCG146 is an LTE internal antenna manufactured by JC Antenna, designed for integration into electronic devices. It features a flexible printed circuit (FPC) form factor with a 10mm rigid section to facilitate mounting and connection. The antenna operates across dual frequency bands: 698–960 MHz and 1710–2690 MHz, supporting various LTE standards. It utilizes linear polarization and maintains a characteristic impedance of 50Ω. Key electrical specifications include a gain of 2dBi and a Voltage Standing Wave Ratio (VSWR) of less than 3.0, ensuring efficient signal transmission within the designated RF spectrum.

Antennas RF Feature Summary

• Dual-band operation covering low-band (698-960MHz) and high-band (1710-2690MHz) LTE frequencies
• Integrated FPC design with a dedicated 10mm rigid segment for secure mechanical attachment
• Linear polarization optimized for consistent signal performance in mobile applications

Antennas RF Applications

• LTE-enabled smartphones and tablets
• Mobile broadband dongles and USB modems
• IoT devices requiring cellular connectivity

Antennas RF Procurement Notes

Verify the specific revision suffix or variant code when ordering, as JC Antenna may offer modified versions such as the JCG146-2 with different dimensional or electrical characteristics. Confirm that the 10mm rigid portion length matches your PCB layout constraints. Ensure the connector type on the FPC tail aligns with your board interface. Request the latest datasheet to validate VSWR and gain curves for your target frequency bands before finalizing the bill of materials.

Antennas RF Selection Notes

Select the JCG146 when a compact, low-profile solution is required for LTE connectivity in space-constrained handheld devices. Its FPC construction allows for flexible routing around internal components, while the rigid 10mm section provides a stable anchor point. Consider this model if your design requires coverage across both lower and upper LTE bands without needing separate antennas. Evaluate the 2dBi gain against your link budget requirements and ensure the <3.0 VSWR meets your system's efficiency thresholds.
