Abstract

A planner inverted-F antenna (PIFA) includes a ground plane, a rib-shaped radiation plate installed approximately in parallel with the ground plane, a feeding line installed on the rib-shaped radiation plate, a feeding contact installed on an end of the feeding line, and a ground contact electrically connected to the ground plane.

Claims

1. A planner inverted-F antenna (PIFA) comprising:

a ground plane;

a rib-shaped radiation plate installed approximately in parallel with the ground plane, the rib-shaped radiation plate comprising a rib;

a feeding line installed on the rib-shaped radiation plate;

a feeding contact located on an end of the feeding line; and

a ground contact electrically connected to the ground plane.

2. The PIFA of claim 1, wherein the ground plane is electrically connected to a grounded area of a printed circuit board.

3. The PIFA of claim 1, wherein the rib-shaped radiation plate comprises a line-shaped rib.

4. The PIFA of claim 3, wherein the line-shaped rib extends from one edge to the other of the rib-shaped radiation plate.

5. The PIFA of claim 3, wherein the rib-shaped radiation plate has a cross section having the shape of an open rectangle.

6. The PIFA of claim 3, wherein the rib-shaped radiation plate has a cross section having the shape of a “

V”

character.

7. The PIFA of claim 3, wherein the rib-shaped radiation plate has a cross section having the shape of a semicircle.
