Directivity of a Uniformly Excited N X N Array of Directive Elements.

摘要

The directivity characteristics of a uniformly excited N X N array of high or low gain elements are described. The voltage patterns of the individual elements were assumed to be of the form cos(to the mth power) theta and J sub 1 (K theta)/K theta where m and K are parameters used to vary the element pattern beamwidths (32degrees to 180degrees). Unidirectional element patterns are assumed; i.e.,the radiation pattern in the region 90degrees
