Abstract:
1. A mirror image shielding structure, comprising: a first electronic element having a winding shape, wherein the first electronic element is one of resistors, capacitors, inductors, filters, balanced/unbalanced converters, and couplers; and a ground shielding plane, parallel to the first electronic element, aligned and located under the first electronic element; a medium material formed in between the ground shielding plane and the first electronic element, for electrically isolating the first electronic element with the ground shielding plane; wherein the ground shielding plane is patterned according to the first electronic element thereabove such that the shape of the ground shielding plane is identical to the projection shape of the first electronic element, and extending in the same directions at both ends of the first electronic element, wherein the first electronic element and the ground shielding plane are not connected to each other, and wherein the horizontal size of the ground shielding plane is in between 1.1-1.4 times to that of the first electronic element.
