The future of the car is a connected one, and with that much connectivity comes a whole lot of talking -- cars talking to other cars, cars talking to infrastructure and cars talking to satellites. You might think that would take a thousand antennae, but according to Harman, it won't.

Harman, an automotive supplier, has developed a "multiband conformal antenna" for vehicles that attempts to do it all. Capable of working with 5G networks, the antenna has a whole lot of bandwidth for future connected cars, and it's capable of communicating with just about everything you could imagine a connected car would need to talk to.
