Can I read Array Factor and Nulls Calculation on EtoBox?

Array Factor and Nulls Calculation by Mohammed Khessro is a document available to read on EtoBox.

What is Array Factor and Nulls Calculation about?

The document presents the derivation of the array factor for a linear array of three isotropic sources, resulting in AF(θ) = −j(1 + 2 sin(π cos θ)). It also identifies the angles at which nulls occur in the radiation pattern, specifically at approximately 99.6° and 146.4°. The calculations involve using the sine function and its properties to find these angles within the specified range.
