A power-detecting, null-scanning, retrodirective array for a CubeSat platform

A power-detecting, null-scanning, retrodirective antenna array for CubeSat platforms is presented. The system utilizes several hardware and software enhancements over previous retrodirective array architectures to address the size, weight, and power limitations of the CubeSat structure. Full-duplex retro-directivity is reported at 9.59 and 9.67 GHz for transmit and receive, respectively.
