Revolutionary Deployable Parabolic Reflector for Ka, W, and G-band Operation for Earth Science Mission

A solution for wide bandwidth high frequency (up to 240GHz) deployable reflector is needed to enable a new type of low-cost and platform-versatile Earth Science missions. Deployable mesh reflectors are limited to a maximum frequency of 60GHz due to the mesh limitations (i.e. surface accuracy and reflectivity). Leveraging on a revolutionary deployable solution, the proposed antenna can operate at frequencies up to 240GHz with an overall surface root mean squared error of 31 microns. In this paper, we are assessing the feasibility of this reflector to operate at 238.5GHz. A Ka- and W-band dual-band deployable reflector is proposed achieving excellent efficiency of 69% and 63% at Ka- and W-band.
