Uniform linear antenna array with the plane wave illumination

Formula

\(AF = \sum_{n=1}^{N}e^{j(n-1)(kdcos\theta +\beta )}\)
Where:
The angular wavenumber \(k=\frac{2\pi }{\lambda } \) expresses the number of radians in a unit of distance
N = number of antenna elements
d = distance between the antenna elements
\(\beta \) = relative phase shift
