Analytically-Designed Planar Aperiodic Arrays in the Presence of Mutual Coupling

The analytical design of aperiodic isophoric arrangements comprising broadband dipole elements is considered. It is shown that, thanks to the Almost Difference Setbased procedure, a controlled sidelobe level is achieved despite the massive thinning of the original layout and the presence of highly coupled radiators. Preliminary numerical examples are reported to assess the efficiency and effectiveness of the design procedure, as well as its capability to yield controlled-sidelobes fully-analytical arrangements.
