Abstract :
A thin-film spiral antenna with Bi microbolometer was fabricated on a fused quartz substrate. Detected voltages of the antenna at 94 GHz exhibited a periodic variation with changing the substrate thickness. Detected voltages were almost constant within the change of ~3 dB at 76.9-106.8 GHz.
