An infinitesimal vertical electric dipole of length ' has the current I = Ioaz along its length, and is located symmetrically on the y-axis with its center point at (0, p, 0) and directed along the z-axis. Assume, negligible radius of the dipole. (a) Calculate far-zone electric fields radiated by the dipole. %3D (b) Using MATLAB, plot radiation patterns using normalized E-fields (normalized to its maximum value) in the o = 0, o = 90 and 0 = 90 planes. (c) Analytically determine its maximum directivity, Do.
