We propose an antenna-coupled microbolometer based on the resistive transition of a high {ital T}{sub {ital c}} superconducting film as a detector for far infrared and millimeter waves. Such microbolometers can be mechanically stronger, more easily fabricated, and much faster than conventional bolometric infrared detectors. A design analysis shows that a noise equivalent power of 2.5{times}10{sup {minus}12} W Hz{sup {minus}1/2} is achievable for modulation frequencies up to 10 kHz. The superconducting film must be of high quality with narrow resistive transition and low 1/{ital f} noise.
