A Thin-film spiral antenna coupled with Bi microbolometer operating at 200 GHz band was fabricated on Si3N4/SiO2 membrane. The experimental antenna patterns agreed well with theoretical ones, and wide band characteristic of the antenna ranging from 140 to 220 GHz was obtained.
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.
We examined about the electromagnetic field immunity test system applying the array antenna technology. This system is able to get the electric field uniformity and the high power electric field near the antenna, in a wideband, by the beam forming technology. We constructed an electromagnetic field immunity test system consisting of 64 elements array antenna as a prototype. In this paper, we calculated...
