…of spatial frequencies, and thus the cleanest (lowest sidelobe) point spread function was obtained when the antennas were arranged in the shape of a Reuleaux triangle. Because of that study, pads upon which SMA antennas can be placed were arranged to form four Reuleaux triangles, with the easternmost pad forming a…
