IoT radar beam is set by bending its flexible PCB, and more Fraunhofer gems from Embedded World

March 08, 2019 / Steve Bush

Fraunhofer IZM has re-spun the idea of mechanically-steered radar, and developed a PCB-based IoT radar that can be bent into shape to customise its beam. Called Flex-Radar, its antennas are built into two polyimide wings. Instead of active beam steering which would be too expensive for intended applications, the wings are simply angled by hand during assembly or installation, then held by the enclosure or glued into place. Both wings have 4 x 4 elements, one wing with 16 receive element, and the other with 15 receive and one transmit.
