A prototype wearable smart reconfigurable antenna for the Suit will be built to be used during NASA's EVA operations on lunar surface. The design is based on the Self-Structuring Antenna (SSA) technology utilizing MEMS switches for configuration of the aperture. Electrothermally and electrostatically actuated MEMS were studied via modeling and experiments and electrostatically actuated switches were recommended for use in Phase II due to their low actuation power requirements. The proposed smart antenna offers both adaptive beam steering and MIMO options for increasing the signal to noise ratio (SNR) and extending range. The antenna provides enhanced RF link for surface-to-surface voice, data, and video communication while also supporting contingency voice communication with the Lunar Relay Satellites (LRS). The technology is expected to reach TRL of 6 at the end of Phase II.
