Study of Broadside Linear Array Antenna with Different Spacing and Number of Elements

Abstract

A uniform linear antenna array has all its elements placed along a straight line with same spacing between them. This paper presents the comparative study of the consequences of different spacing and number of elements in terms of array factor, antenna directivity and half power beam-width (HPBW) for Broadside array. The results were obtained through the antenna parameters algorithm and simulations were done with MATLAB. The algorithm has been designed to operate with random number of elements with specific spacing. Output was studied with 2, 10, 40, 70 and 100 numbers of elements having specific spacing. The particular spacings are 0.1λ, 0.25λ, 0.5λ and 0.75λ. With the increase of number of elements and spacing between them, the directivity and array factor increases.
