Abstract :
A thin-film 2-arm spiral antenna with Bi microbolometer operating at 100 GHz band was fabricated. In the video detection, detected voltages, which were proportional to the power of signal wave at 94 GHz and a bias current, were obtained. DC sensitivity of the microbolometer was about 35 W-1.
