HARMAN Smart Conformal Antenna
The All-in-One Connectivity Solution

​Smart Conformal Antenna is the automotive industry's only all-in-one antenna assembly which can be mounted inside the vehicle flush with the roof. Combined with 5G technology, this results in a sleek package with improved connectivity and aerodynamics.

High on performance and design, low on weight and cost, this unique solution supports the automotive needs of the digital age, including autonomous driving, OTA updates, and future-ready E/E architectures. ​

Stealth + Speed + Performance

The modern automotive consumer wants next-gen in-cabin experiences such as vehicle to everything, augmented reality, and autonomous driving - all of which require high-speed, low-latency connectivity. The result? More antennas on the roof of a vehicle. This poses a challenge for designers, engineers, and aerodynamicists. 

To address this, HARMAN engineering teams have developed the Telematics Control Unit (TCU)/Smart Conformal Antenna. Integrating the latest 5G technology with up to 14 different vehicle antennas in one sleek package, it allows designers to retain clean exterior lines while delivering superior connectivity on-the-go. The invisible stealth design utilizes an optimized antenna layout and the latest wireless technologies to minimize signal loss and offer next-gen experiences that are responsive, reliable, and dependable.
