Summary:
Millimeter-wave penetrates various materials like clothes, fire and fog [1]-[3]. Millimeterwave imaging is applied to detection of weapons under clothes, discovery of victims in afflicted area, and monitoring of driving environment. High sensitivity and wideband are demanded in millimeter-wave detector module, because the weak thermal radiation from object is received to obtain image in passive imaging. We propose a millimeter-wave detector module for simple structure, low profile and easy manufacturing [4]. We designed a millimeter-wave detector module at two frequency bands around 70 GHz and around 90GHz for imaging test in these frequency bands. Miniaturization of detector module and improving of resolution is expected at higher design frequency. Configuration of the detector module is presented and performances of these components are reported in this paper.
