RFID PATCH ANTENNA WITH COPLANAR REFERENCE GROUND AND FLOATING GROUND

摘要

PROBLEM TO BE SOLVED: To provide a wide band patch antenna which is thin and small with a low cost.;SOLUTION: In a patch antenna, a main radiation element 110 is placed in a common geometric plane, or substantially the same plane, with a reference ground element 120, or the main radiation element and the reference ground element are placed in two parallel planes which are closely spaced each other and are separated by a dielectric property laminate 100, and there is little or no overlap between the main radiation element and the reference ground element. A floating ground plane 130 may be implemented in addition to the reference ground element.;COPYRIGHT: (C)2013,JPO&INPIT
