“…An interesting property of metasurfaces is that they can be engineered to synthesize an arbitrary wavefront in an allelectronic manner. Beam-synthesis is an important application of EM wave-control and has been studied extensively within the field of antennas and propagation, particularly in the context of phased arrays [6]- [8]. Conventionally, beam-synthesis requires an array topology, in which an array of antennas, typically sampled at a Nyquist limit, is used.…”

We present the concept of holographic beam forming metasurface antenna for CubeSat platforms at X-band frequencies. The proposed metasurface topology exhibits a flat-panel system layout, particularly desirable for integration with CubeSat platforms without a hardware-intense deployment mechanism for launch. It is shown that appropriately interacting the guidedmode (or reference-wave) with a metasurface layer makes it possible to realize the radiation pattern of interest as an objective function-similar to an optical hologram-without the need for dedicated phase shifting circuits. The full-wave simulations of the designed metasurface layer integrated with a 1U CubeSat reveals a high-fidelity beam-control with an aperture efficiency greater than 40% at 10 GHz operating frequency.
