A separate‐type two‐dimensional 8 × 3 folded‐slot array antenna was fabricated using photolithography and wet etching, and the receiving properties for 94‐GHz millimeter wave radiation were investigated theoretically and experimentally in order to improve the receiving gain of a separate‐type slot antenna. The fabricated folded‐slot array antenna had a power gain of 12.5 dBi which was 10.5 dB larger than the single slot antenna at 94 GHz. This power gain was almost the same value as a monolithic‐type 8 × 3 slot array antenna within 0.5 dB. © 2000 Scripta Technica, Electron Comm Jpn Pt 1, 84(1): 91–98, 2001

SUMMARYSlot antenna-coupled thin-film warm carrier devices were fabricated, and the detection properties were investigated at 94 and 700 GHz. Two-dimensional 8 × 3 slot antenna arrays fed by a coplanar waveguide were used as the antennas. The thin-film antennas were fabricated with a photolithographic method, and the warm carrier detectors, which have a contact area of 8 × 10 -10 cm 2 , were fabricated with an electron beam lithographic method. The experimental results indicate that the fabricated devices receive the far-infrared radiation with antenna and rectified it with nonlinear I-V characteristic. By changing the antenna from the single-slot antenna to the two-dimensional 8 × 3 slot antenna array, the detected sensitivity improved by 11 dB.
