Abstract

With the long term aim of developing a NadirSAR quadrotor UAV system specialized for monitoring broad acre grain fields, a large aperture load bearing antenna to use as the main structural element was sort. Here initial design work is presented on a candidate short f/D parabolic reflector antenna. An optimized splash plate feed and a dual mode coaxial horn were designed for the 10 to 10.5GHz experimenter’s band and were fed by aluminum waveguide. Both feeds gave better than 30% aperture efficiency on a low cost 11.6l0 diameter reflector that had a focal length of f/D=0.27.
