Abstract :
In this communication we analyze a patch fed by a coplanar waveguide cut on the ground plane and centered with respect to the non-resonant length of the patch. The absence of the radiating even mode of the coplanar waveguide in such a symmetric structure allows to design an antenna without back-radiation effects. The analysis is made using the mixed potential integral equation (MPIE) formulation of the method of moments.
