Antenna types for Automobiles
Shark-fin antennas
Shark-fin antennas are fixed on the roof of a vehicle. They are designed to include various functions, such as Wi-Fi/Bluetooth, GPS/GNSS, TEL (single and MIMO) and V2X communication. They enable autonomous driving functions and eCall, which increase the safety of all road users.
Depending on the antenna size, AM/FM can also be included. Regional specifications, such as SDARS, can be taken into account. We collaborate closely with our customers to develop optimal customized solutions for connected cars.
Rod antennas
Rod antennas are lightweight, cost-efficient, and flexible. They consist of a base and rod, which complement each other.
For example, the rod contains AM/FM, DAB III, and lower frequency TEL functions. Additional functions, such as high frequency TEL and GNSS, are built in the base. Regional specifications, such as SDARS, can be taken into account.
With rod antennas autonomous driving functions and eCall can be realized. Together with our customers we develop optimal customized solutions for connected cars.
Hidden antennas
Hidden antennas are used in order to avoid disturbing car outlines. Examples of this are GPS/GNSS antennas, which are placed inside the rear spoiler. They enable accurate positioning of a vehicle for autonomous driving and eCall. We evaluate customer-specific requirements and incorporate them in our antenna design.
Hidden antennas are also placed in areas such as the dashboard, mirrors and glass. The preferred positioning of GPS, GNSS and TEL antennas is the dashboard. They are essential for connected services such as Over-The-Air updates (OTA) and Cloud Connectivity. NFC access systems are another variant of hidden antennas. We configure NFC antennas for access systems according to customer-specific requirements.
