Range adaptable antenna system for autonomous vehicles

A radar system for use in an autonomous driving vehicle, comprising:

• an antenna module to radiate a transmission signal with a range adaptable antenna in a plurality of directions and generate radar data capturing a surrounding environment, the range adaptable antenna comprising a plurality of superelements, wherein a set of superelements in the plurality of superelements is connected to a set of switches for deactivation;
• and
• a perception module to detect and identify a target in a surrounding environment of the autonomous driving vehicle from the radar data and to control the antenna module based on the detected target.

A range adaptable antenna module for use in an automotive radar, comprising:

• a range adaptable power divider layer comprising an array of transmission lines to divide the RF transmission signal into a plurality of transmission signals, wherein a set of transmission lines from the array of transmission lines comprises a set of switches;
• and
• an antenna layer comprising an array of superelements coupled to the array of transmission lines, wherein the set of switches is adjusted to deactivate a set of superelements in the array of superelements.
