Instead of using pattern, which is designed for normalized far‐field plots (often in dB), you should use EHfields. EHfields computes the actual electric and magnetic field vectors (in V/m and A/m) at user‐defined observation points. This function lets you specify the coordinate system (e.g., Cartesian, spherical, or cylindrical) so you can input your desired positions accurately. It works for both near-field and far-field calculations, so you can obtain the real, unnormalized field values you need for your analysis.
