The FAKRA connector was originally an antenna standard in Germany. Later, it was extended to the function of transmitting signals with radio frequency characteristics, such as video and navigation. Connectors that meet this standard are called FAKRA connectors. The RF frequency of the FAKRA connector can reach 6GHz. Coaxial cables are generally used, with single wires and single cores. At present, FAKRA connectors have become the main solution for automotive RF applications. This includes aspects such as GPS systems, satellite radios, in-vehicle Internet access, and engine management.
