Discontinuity in the waveguide (a) and equivalent circuit (b). a, b: the dimensions of the first waveguide (the substrate of the antenna). c, d: the dimensions of the second waveguide (patch antenna). Y1, Y2: the equivalent permittivity expressing the first and second waveguide. J1: the current resulting from the propagating modes in the first waveguide. J2: the current resulting from the propagating modes in the second waveguide. E1: the voltage source resulting from the propagating modes in the first waveguide. E2: The voltage source resulting from the propagating modes in the second waveguide. E: the voltage source expressing the discontinuity in the waveguide.
