Enhancing antenna directivity is essential for space communication like NASA’s Artemis lunar mission, where maximizing electromagnetic energy efficiency is crucial for long-range space communication systems. Enhancing antenna directivity is crucial for modern long-range applications such as radar and space systems, where maximizing the efficient use of electromagnetic energy is critical. One way to increase directivity is by either increasing the antenna element or using an array of elements. Nevertheless, increasing the antenna size often leads to a significant increase in SWAP-C (size, weight, area, power and cost), due to increased hardware at RF front end (RF-FE) either in terms of RF chains or complex beamforming circuitry. A practical solution for these missions is integrating a lens with the antenna structure, which improves directivity without adding additional hardware to the RF-FE. Of course, in-situ 3D printing of RF components such as antennas, lenses, and other communication systems is critical for rapid adaptability to changing mission requirements, reducing dependency on Earth-based supplies. This imposes certain restrictions to the lens type and their design aspect.
