Abstract:

Structure scattering analysis of microstrip antennas mounted on a finite curved surface is presented via method of moments. Using the equivalence principle, the coupled volume-surfaced integral equation of arbitrary curved surface conformal microstrip antenna is formulated, in which the free space Green’s functions is used so as to obviate the analytic expressions and accurate computation of the dyadic Green’s functions. In Galerkin method, the SWG and RWG basis function are used for the dielectric and the conductor surface respectively. According to the continuity equation of electric current on the interface between conductor and dielectric, an efficient scheme is proposed to reduce the unknown numbers and condition numbers of the matrix equation.
