ATI2458G-4717-55

Antennas RF Overview

The ATI2458G-4717-55 is a dual-band PCB trace antenna manufactured by YIC, designed for wireless communication applications. It operates across two frequency ranges: 2.4GHz to 2.5GHz for Wi-Fi and Bluetooth, and 5.15GHz to 5.85GHz for 5G Wi-Fi. The component features a maximum height of 0.016 inches (0.40mm) and provides a gain of 2dBi. It utilizes an I-PEX connector interface and employs adhesive mounting methods. The physical dimensions are specified as 55mm in length, making it suitable for compact device integration.

Antennas RF Feature Summary

• Dual-band operation supporting both 2.4GHz and 5.8GHz wireless standards
• Low profile design with minimal height for space-constrained applications
• Stable performance characteristics with low temperature coefficient
• Adhesive mounting mechanism for secure PCB attachment

Antennas RF Applications

• Wi-Fi routers and access points
• Bluetooth-enabled peripheral devices
• Zigbee™ smart home modules

Antennas RF Procurement Notes

Verify the specific I-PEX connector type and adhesive backing specifications against the official YIC datasheet before integration. Confirm that the 55mm form factor aligns with the target enclosure constraints. Ensure compatibility with the intended RF circuit impedance. Cross-reference the manufacturing lead time requirements with production schedules to avoid delays.

Antennas RF Selection Notes

Select this component when dual-band coverage for 2.4GHz and 5.8GHz is required within strict height limitations. The 2dBi gain offers adequate performance for short-range indoor communications. Consider the adhesive mounting method if soldering options are unavailable or undesirable. Validate that the I-PEX interface matches the existing board layout and connector footprint.

Antennas RF Part Context

This antenna belongs to YIC's ATI2458G series, which includes variants optimized for different frequency bands and form factors. The series targets IoT and consumer electronics markets requiring reliable wireless connectivity. Other models in the family may offer single-band operation or different connector types, but this specific part number addresses dual-band needs with a defined physical profile.

Antennas RF Replacement Considerations

Direct substitutes include other YIC dual-band PCB antennas with matching I-PEX interfaces and similar gain ratings. Verify that any alternative maintains the 2.4GHz/5.8GHz frequency coverage and adhesive mounting capability. Ensure the replacement part meets the same mechanical height constraints to fit within the original design envelope.
