Array of two parallel dipoles – pattern multiplication. Repeat the previous MATLAB exercise but for an array of two parallel Hertzian dipole antennas (dipole axes are perpendicular to the array axis, while the interelement spacing and phase shift are d = λ/2 and δ = 0, respectively).

HINT:

Since the dipoles are not along the array axis, if we keep the array axis coincident with the zaxis of a global spherical coordinate system in which the analysis is performed, then the dipoles will not be z-directed, and vice versa. So, let us adopt the system with dipole antennas parallel to the x-axis. Obviously, we cannot use now the expression in Eq.(12.17) for the element characteristic radiation function, and what we need rather is the one for an x-directed Hertzian dipole placed at the coordinate origin or reference point (O) of the array, which is given by . Implement this function and use functions ArrayF and patternMultiplication (in the same way as in the previous MATLAB exercise).
