Hello,
I'm sending you this e-mail because I've some concerns about how to predict the electric field by an array of dipoles. I've a colinear dipoles, feeding by the same amplitude and phase's current. I'm solving the problem by calculating the power that is radiating by an element (one dipole) and after that multiplying by the gain, g, (the array's gain: for 4 dipoles is about 8 dB) and applying the formula: E=sqrt(30)*sqrt(PIRE)/d . Is that solution correct? I've other point of view: I can calculate the total power that are feeding the array (Pa), then multiplying by the gain, g, I've the PIRE that I want. After that it's just apply the same formula. Of course the two results are diferent each other. May have some explanations or links to find what's the best solution? Thank you very much Best Regards
