Summary:
This paper discusses an evaluation of a fan beam carbon fiber reinforce plastics (CFRP) offset parabolic reflector antenna for W-band millimeter-wave radar systems. For the radar applications with mechanical azimuth scanning systems, it is required to achieve a narrow azimuth radiation pattern, as well as a relatively wide elevation pattern. Firstly, the CFRP parabolic reflector, which has the aperture size of 327 mm × 300 mm, is fabricated using 1K woven fabrics. Next, the maximum gain and radiation pattern are measured between 75 GHz and 110 GHz. Finally, the CFRP parabolic reflector with the 15.0 mm-diameter conical horn feeding confirms elevation fan beam characteristics and a gain of almost 40 dBi at 96 GHz.
