Patch antenna with electromagnetic shield counterpoise

摘要

A patch antenna includes a radiating element positioned on one side of a printed circuit board and an electromagnetic shield positioned on the opposite side of the printed circuit board. The electromagnetic shield forms at least a portion of a counterpoise and is connected to the ground of the PCB in at least one location. Design flexibility in positioning the antenna within a portable communication device is maximized while the size of the portable communication device is minimized.
