Advanced UHF SATCOM Satellite Protection Features

The proposed project involves the integration of an Artificial Magnetic Materials (AMMs) with a planar antenna system with the system exhibiting multiple RFI mitigation features. The system will protect against spatial RFI by using a metamaterial surface to reduce the beamwidth of the radiation pattern. The antenna systems will be designed as an array of supercells consisting of the radiating element and the metamaterial reflector. Cells would be configured using a butler matrix and create a focused beam which would further reduce spatial RFI. The proposed technology will provides a Size, Weight, and Power (SWaP) advantage over SATCOM antenna systems currently deployed in CUBESATs. The applications for this technology are focused for CUBESATs and satellite-based communication systems.
