Normal and emergency communication with the world
Underneath the rear bumper cladding is a pair of LTE antennas. “The one on the right is dedicated to mobile data services and, together with the antenna in the roof fin, ensures the best possible data flow. One would not be enough – the antenna is either receiving or transmitting at a particular moment, because it cannot handle both at the same time. That’s why they’re doubled up, so that the car’s communication with its surroundings is as fast, smooth and high-quality as possible, even at higher data volumes. In addition, the rooftop LTE antenna also serves the needs of the emergency e-Call system. This is mandatory in many regions, so even cars with lower equipment levels have GNSS and LTE antennas in the roof fin so that the car knows its location and can send it to emergency responders in a special SMS,” Navrátil explains.

The left antenna in the rear bumper serves as support for the Phonebox equipment. This is a module in the dashboard that enables inductive wireless charging of mobile phones. However, it is rather obscured there, so an outdoor signal finds it hard to reach. This antenna therefore essentially brings the mobile signal closer to the phone in the cockpit.

All European ŠKODA models today use the set of antennas described here, and you won’t see a classic roof-mounted rod antenna on them anymore. With one exception. “That’s the FABIA. What is otherwise caught by the structure in the fifth door, i.e. the AM, FM and DAB signal, is dealt with by a roof bar on this compact car. The FABIA has it on the roof even if it is equipped with navigation. In this case, the antenna bar has a larger base that contains the GNSS module,” adds Svoboda.
