This pair of review articles describes various synthesis techniques which have proven useful in determining the excitations of arrays that are to produce desired radiation patterns. Part I deals with equispaced linear arrays and Part II with planar arrays. The latter may have its radiating elements disposed in rectangular, triangular, or circular grids, and the boundary can be arbitrary, e.g., rectangular, circular, or elliptical. Sum and difference patterns (characterized by lobes interspersed by deep nulls) and shaped patterns (such as cosecant-squared) are discussed. Only the array factor is considered; the resulting patterns need to be multiplied by the element factor.
