Directivity of a Uniformly Excited N X N Array of Directive Elements.
Abstract
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 (32 degrees to 180 degrees). Unidirectional element patterns are assumed; i.e., the radiation pattern in the region 90 degrees < theta < or = 180 degrees has been neglected. The directivity is plotted as a function of the element spacing in wavelengths with N as a parameter (N = 2, 3, 4, 5, 6, 8, 10, and 12). (Author)
