Abstract
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.
Claims20
A patch antenna comprising:
- a radiating element positioned on a first side of a printed circuit board;
- and
- a electromagnetic shield positioned on an opposite side of the printed circuit board and forming at least a portion of a counterpoise of the patch antenna.
A patch antenna in accordance with 1, wherein the radiating element and the electromagnetic shield at least partially form a planar inverted “F” antenna (PIFA).
A patch antenna comprising:
- a printed circuit board having a first side and a second side;
- a planar radiating element connected to the first side of the printed circuit board and positioned at least partially over an opening in the printed circuit board;
- and
- an electromagnetic shield connected to the second side of the printed circuit board and positioned at least partially under the opening, the electromagnetic shield forming at least a portion of a counterpoise of the patch antenna.
A mobile communication device assembly comprising:
- a printed circuit board having a first side and a second side;
- a plurality of electrical components mounted to the printed circuit board;
- a planar radiating element connected to the first side of the printed circuit board and positioned at least partially over an opening in the printed circuit board;
- and
- an electromagnetic shield connected to the second side of the printed circuit board and positioned at least partially under the opening, the planar radiating element and the electromagnetic shield forming at least a portion of a patch antenna.
