Computation of far field radiation :

From equation (7.7) to (7.9) we have seen that solution for and can be obtained provided solution of is unknown for a given . Further while computation of radiated fields for a Herzian dipole, in equation (7.23a) and (7.23b) we have neglected the higher order terms of and retained only those terms having variation. In fact, once is known the radiation field components can be completed for the far field region as:

The relationship stated above equation (7.37a) - (7.37f) may be verified for a Herzian dipole using equations (7.22), (7.24a) and (7.24b).
