Mutual Coupling of a Slot with a Dipole Antenna

Aparameter is defined from which may be obtained the mutual coupling between a radiating slot, cut in a plane perfectly-conducting sheet, and a dipole fed at its base on the conducting plane. Using a slot cut in a sheet of copper and fed by a waveguide, experimental values of this parameter were obtained for various positions of the dipole relative to the slot. These values are plotted and compared with the theoretical ones, very good agreement being obtained.
