SDCP.5900.12.4.A.40 Antenna DSRC, C-V2X SMD/SMT patch for Automotive Rearview Mirror Back Mount, In-Vehicle Window Mount, Embedded in Roadside Transceivers

This compact embedded ceramic patch antenna is designed for DSRC systems in the 5.9GHz band. Its directional performance supports short-range, low-latency vehicle communications, while circular polarization helps maintain more consistent link quality when the device orientation changes.

• Directional patch design: helps extend communication range compared to omnidirectional solutions
• Circular polarization (RHCP): improves stability on moving platforms where orientation can vary
• Embedded form factor: small size for integration into space-constrained enclosures and assemblies
• SMD/SMT termination: suited to high-volume manufacturing processes

Typical use cases include: Automotive Rearview Mirror Back Mount, In-Vehicle Window Mount, and Embedded in Roadside Transceivers.
