Total radiation pattern in antenna arrays
The first is still correct, and can be evaluated at any position.
The second is true only at broadside, when $\theta=0$.
In your attempts, do you find that $\vec{E}_{total}$ is the same in all directi …

What is the radiation pattern of a center fed dipole on the ground?
The best way to answer this is with a NEC simulation of a dipole on the ground.
Using a "Pastoral, medium hills and forestation" ground, Conductivity 0.006 S/m Relative Permittivity 13.
