Abstract :
The effect of a parasitic dipole above a waveguide slot antenna is shown analytically and verified experimentally. The E-plane radiation pattern is shown to be rather sensitive to the change of dipole length, and an equalised E- and H-plane pattern is obtained by choosing a proper length of dipole.
