Resonant length of electric dipole located inside dihedral corner reflector

For an electric dipole length 2l located in the bisector plane of a thin perfectly conducting corner reflector with infinite side sizes both the RS and X parts of the input impedance and the dipole resonant length at X = 0 as functions of the dipole-to-corner distance S at different flare angles were calculated via the method of images and induced electromotive forces. It is shown that with varying S the dipole resonant length is decreasing as well as increasing with respect to the half wave. Effect is more noticeable than have less a flare angle and bigger the thickness of a dipole.
