ACR1004GC

Antennas RF Overview

The Abracon ACR1004GC is a surface-mount, multi-band GNSS and GPS L5 chip antenna designed for high-precision positioning applications. It operates across two frequency bands: 1.166 GHz to 1.186 GHz and 1.561 GHz to 1.61 GHz. The component features a peak gain of 2.8 dBi in the lower band and 1.9 dBi in the upper band, with a nominal impedance of 50 ohms. Its compact physical dimensions are 10 mm in length, 4 mm in width, and 1.5 mm in height. The unit supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Antennas RF Feature Summary

• Supports dual-band operation for both standard GNSS signals and GPS L5 frequencies
• Provides centimeter-level accuracy through high-efficiency radiation patterns
• Utilizes a low-profile loop antenna design suitable for space-constrained PCB layouts

Antennas RF Applications

• High-precision automotive navigation systems
• Geospatial surveying equipment
• Smartphone and mobile device positioning modules
• IoT tracking devices requiring enhanced location accuracy

Antennas RF Procurement Notes

Verify that the specific order matches the ACR1004GC part number to ensure dual-band GNSS and GPS L5 capability. Confirm that the receiving facility accepts surface-mount components with the specified 10mm x 4mm footprint. Ensure that the procurement documentation explicitly states compliance with RoHS regulations. Cross-reference the manufacturer's latest datasheet to confirm the current revision status before finalizing purchase orders.

Antennas RF Selection Notes

Select this component when centimeter-level accuracy is required over standard meter-level GNSS solutions. The dual-band support makes it suitable for environments where signal interference or atmospheric delay correction is necessary. Consider the 1.5 mm profile height for integration into thin consumer electronics or wearable devices. Ensure the host circuit board provides adequate ground plane clearance to maintain the specified 50-ohm impedance and radiation efficiency.

Antennas RF Part Context

This antenna belongs to Abracon’s ACR series of multi-protocol PCB antennas. It is distinct from single-band variants by its inclusion of the L5 frequency band, which offers improved robustness against ionospheric delays. The product line focuses on providing reliable connectivity for global navigation satellite systems in compact form factors suitable for modern electronic assemblies.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing RF front-end designs if substituting with other multi-band GNSS antennas from different manufacturers.
