Is it physically feasible to design antennas with extremely high gain, such as 131‑dBi?
Some literature and proposals suggest antennas with gains exceeding 130?dBi, typically for deep-space communication or radio astronomy. I want to understand the physical constraints—size, aperture, diffraction limits, efficiency, and fabrication challenges—that make such designs feasible or practically unattainable.
