PROPERTIES OF THE TRIANGULAR LATTICE ARRAY

Abstract

A new type of array consisting of elements arranged in a triangular lattice is studied in this report. The quarry has radiation characteristics similar to those of a tapered array but does not require tapered excitation. A phased array of an arbitrary triangular lattice configuration is formulated using the vector model. It is applied to a special case of an isosceles triangular array. The directivity of the array is derived and expressed in a compact form, whereby its enumeration becomes a routine procedure for any total number of elements. A general method of evaluating the mutual coupling terms involving two inclined short dipoles is developed. Numerical results are presented and discussed as regards the radiation patterns and directivities of an isosceles triangular lattice array with its varying parameters such as the spacings between the adjacent elements and rows of elements, the phasings of the elements, and the size of the array.
