The E-plane is any plane that contains the E-field and the direction of maximum radiation from the antenna. As
an example, consider a
short dipole, the electric
fields are given by:|

The E-plane is any plane that contains the E-field and the direction of maximum radiation. Hence, the E-plane in this case is any plane that contains the z-axis (xz plane, yz plane, etc). The E-plane cut is not unique in this case, but a plot of the radiation pattern given in the E-plane would be a function of the polar angle (), which is measured off the z-axis.
