Dual-Mode Patch Filter with Metal Wall Structures

Dual-Mode Patch Filter with Metal Wall Structures

A dual-mode patch filter with metal wall structures is presented. The proposed structure consists of substrate 1 with metal wall structures and substrate 2 with a patch resonator. Because the symmetry of the structure can be perturbed by both long and short strips of the metal wall structures, the...
