Abstract

Detailed procedure for Green's function derivation of an annular waveguide is presented in this paper for the first time. The proper components of the electromagnetic fields along with their corresponding Green's functions will be derived in a useful and applicable form. Based on the derived Green's functions, proper set of integral equations are derived in a novel general form which their MoM solution will lead to complete slot field distribution in the annular waveguide slot antenna (AWSA). The proposed theory would be found of high value in circuit modelling and array design of such novel antenna structures in the future.
