The goal of this work is the analysis of a compact array of slot antennas on a cylindrical metallic cavity, fed by microstrip lines in a plane inside the cavity. We derive the Green’s functions for both electric and magnetic fields in the cavity by projecting the excitation currents on a modal expression of current sheets derived from waveguide expressions. This allows an easy and intuitive computation of the fields inside the cavity.
