Impact of spacing and number of elements on array factor

Abstract

The impact of spacing and number of elements in terms of gain and half power beam-width (HPBW) are shown in this paper. The antenna's gain is depending on two parameters which are number of elements and element spacing. These measurements were measured by array factor's algorithm. The algorithm has been designed to operate with 2, 3, 4 and 10 number of elements at the each specific spacing. The particular spacing are 0.1λ, 0.25λ, 0.5λ and 0.75λ. It is observed that the HPBW and number of side lobes is increased as spacing of elements are increases. And the gain is maintains in the same condition.
