Development of W-Band Millimeter-Wave Links for Nanosat Applications
Abstract
CubeSats have evolved from an educational platform allowing universities to develop cost effective flight- ready spacecraft to standard platforms which allow for advanced technology demonstrations. Most CubeSats are used for earth science observation including optical, infrared, and microwave imaging for things such as atmospheric properties including clouds and precipitation, land topography and soil moisture, ocean surface salinity and temperature, snow and ice cover, and gravity and magnetic field monitoring. CubeSats occupy the low earth orbit (LEO) at 500 km above the earth, with the ceiling at 2180 km. All of these remote sensing applications generate large amounts of data, which require a SATCOM downlink with high data rates. We have proposed the development of a CubeSat beacon which will allow for high data rate downlinks for remote sensing applications, as well as the characterization of channel prorogation in the W-Band. The goal of the project is the development of W-band millimeter wave links for CubeSat applications. To accomplish the task we have proposed two solutions. First solution is the development of W-band feed horn with polarizer structure for an offset reflector antenna. The second solution is the development of the W-band circular polarized series fed single plane beam steering array antenna with 4-bit phase shifter for CubeSat applications.
