Code 3.2: Array Factor for Uniformly Spaced Array with Linear Phase Distribution

Code Name: ArrayFactor_LinearPhaseDist.m

Description: Code computes the array factor as defined by Eq. (3.97) for any amplitude distribution.

Input Variables:

  N:    Number of array elements
  ai:    Amplitudes of feeding coefficients, i = 0 to N − 1 (arbitrary units)
  d:    Spacing between adjacent elements (m)
  f:    Frequency (GHz)
  δ:    Incremental phase delay (degrees)

Output Products:

  Plot:    Normalized array factor Fa(Θ) versus Θ
