The magnetic field inside the cavity was considered as the field of sum of the eigenwaves in the waveguide with a three-layer dielectric. The electric field distribution of each eigenwave was used as the basis function in the Galerkin procedure of finding the unknown amplitude coefficients. The effect of the parameters of the dielectric layer on its resonance properties was studied for the longitudinal slot with a dielectric layer located in slot center.

The radiation resistances are calculated by the Poynting vector method as the functions of the monopole's surface impedance and the sizes of monopole and screen.
