Arrays are several antennas connected and arranged in a regular structure to form a single antenna. Arrays produce radiation patterns that when combined have characteristics that individual antenna radiation patterns cannot produce.
Types of array elements in Antenna Toolbox™ array library
Active or scan impedance, array factor and pattern multiplication, coupling matrix, isolated or embedded element pattern
Side lobe control, beam scanning
Grating lobes are the maxima of the main beam, as predicted by the pattern multiplication theorem.
