The integrated circuit chips are in contact with (such as disposed on) the flexible substrate and/or the electrically conductive circuit paths. The flexible radar system generates and receives wireless signals during conditions in which the circuitry disposed on the flexible substrate is bent to one or more non-planar states. | 2021-09-30 |
