The input admittance or a rectangular slot which is backed by a recLangular cavity has been recently computed using variational techniques [Galejs, 1963]. The omewhat similar problem of rectangular slots cut in waveguide walls has been treated using the Hallen's method of antenna analysis [Hallen, 1938; Watson, 1947 ; Stevenson, 1948]. Broadband Slotted Coaxial Broadcast Antenna Technology impedance cancellation to a slot radiator is by placing a complementary impedance in the same circuit as the slot. Babinet’s principle, put into antenna terms by H.G. Booker in 1946, relates the fields and impedance of an aperture antenna to its dual [3]. The dual of a slot would be a dipole as shown in Figure 3.
Open slot antenna in a small ground plane Abstract: The impact of a finite ground plane on an open-slot antenna performance is reviewed and the far-field pattern behaviour is clarified. The pattern of this slot configuration is fundamentally different to its complementary dipole. Here, a parametric study of a slot antenna is presented including

Slot Antenna - an overview | ScienceDirect Topics Babinet's Principle. One may view a slot antenna to be physically complementary to a strip dipole antenna consisting of a metal strip of the same. shape and size as that of the slot. The complementary strip dipole is to be excited by a voltage gap, breaking across the strip at the same position where the slot antenna is excited. If the slot antenna is superimposed on its complementary dipole Radar Basics - Slot Antennas The fields of the slot antenna are almost the same as the dipole antenna, but the field’s components are interchanged: a vertical slot has got an horizontal electric field; and the vertical dipole has got a vertical electrical field. The impedance of the slot antenna (Z s) is related to the impedance of its complementary dipole antenna (Z d
The skeleton slot antenna used to be pretty popular on 2-meters and higher frequencies. J-Beam Ltd. (an antenna company in the U.K.) used to make several different models for 2-meters with different numbers of parasitic elements.
“Slot Aerials and Their Relation to Complementary Wire Rigorously, a "slot antenna" should have a much narrow width against its length and operating wavelength so that it could be recognized as a complementary case of a 1-D, linear electric dipole. Self-complementary antenna - Wikipedia
