Consider the two Hertzian dipoles shown below: J1 ? J2 The current densities of the dipoles are specified by the phasors: 10/

Consider the two Hertzian dipoles shown below: J -a h=1 2 h Assume A =1, a = -, h= J2 The current densities of the dipoles are specified by the phasors: Z 3.(P)-21d8(7-2), 3(7)-2 18 Ae" 8(7+2) = Id X (a) Can you figure out the angular location of all the nulls and maxima of the radiation pattern by physical reasoning, without calculating radiation pattern explicitly? Explain your reasoning. (b) Generate a plot (for example, using Matlab) of the 3D radiation pattern p(0.6), and verify that your predictions in (a) are correct.
