Bluetooth® Channel Sounding: Johanson antenna integrated into the new Nordic nRF54L15 reference design

High-precision distance measurement between Bluetooth devices is one of the most exciting new use cases for Bluetooth® LE 6.0: with Channel Sounding, distances between connected devices can be determined with high accuracy – providing the basis for secure proximity detection, real-time location systems (RTLS) and digital key systems. Johanson Technology, whose antenna 2450AT18D0100001E is now utilized in Nordic Semiconductor’s official Bluetooth® Channel Sounding reference design based on the nRF54L15, significantly simplifies the entry into this technology for developers.

Key specifications of the 2450AT18D0100001E:

• Passband: 2.4 – 2.5 GHz

• Package size: SMD, EIA 1206

• Construction: LTCC (Low Temperature Co-fired Ceramic), high detuning resistance and thermal stability

• Peak gain: approx. 1.5 dBi

• Power capacity: up to 2 W

• Maximum profile height: 1.20 mm

• Mounting: Center-edge, suitable for circular PCBs or thin edges

• RoHS compliant, AEC-Q200 qualified variant available

Typical applications for Bluetooth® Channel Sounding:

• Asset tracking and RTLS

• Digital keys and access control

• Smart locks and connected building automation

• Matter and Thread devices in smart homes

• Wearables and medical monitoring

• Industrial automation and warehouse tracking

• Robotics, drones and autonomous systems

As the antenna is already an integral part of a validated reference design, developers can bypass a significant portion of the otherwise required antenna evaluation and PCB optimization – providing a clear time-to-market advantage during RF certification and transition to series production.
