Optimization Design of a Small Aperture Cassegrain Antenna for 8mm Band Detector

Jiso Jiso Fan, Li Wu, Shu Sheng Peng

Abstract

In this paper, a small aperture Cassegrain antenna of 8mm band detector is optimally designed, whose main reflector diameter is limited at 96mm (diameter less than 30λ). After design and processing, this antenna measured results show its gain is 26dB, the sidelobe level is close to-12dB and-3dB beam-width is 4.8 °.These are consistent with simulation optimization results.
