High-Frequency CubeSat Platform Scattering Using Higher-Order Method of Moments

We present a 10 cm offset reflector antenna mounted inside a 6U CubeSat platform and analyze the bare reflector and three reflector + CubeSat platform configurations in W band (86 GHz), where the CubeSat platform is electrically large. Using higher-order MoM/MLFMM techniques, we obtain accurate antenna patterns and quantify the significant impact that any of the CubeSat platforms in this case have on the antenna pattern. In addition, our study demonstrates that details of the CubeSat platform impact the patterns to a lot smaller extent.
