Abstract
Provided is a planar inverted F antenna including a ground surface having a finite plane and formed of a conductive material, an antenna body at a certain distance from the ground surface and transmitting and receiving radio waves, a feed line for electrically connecting the ground surface and the antenna body, a ground pin for grounding the antenna body to the ground surface, and at least one auxiliary plate disposed between the antenna body and the ground surface. Therefore, it is possible to readily overcome design restrictions of the antenna in keeping with the slimming and miniaturization of mobile communication terminals by installing the auxiliary plate between the ground surface and the antenna body.

A planar inverted F antenna comprising:
- a planar ground surface formed of a conductive material;
- an antenna body disposed at a first distance from the ground surface and configured to transmit and receive radio waves, the antenna body having a length longer than a width;
- a planar feed line configured to electrically connect the ground surface and the antenna body;
- a ground pin disposed at a first end of the antenna body length, the ground pin configured to ground the antenna body to the ground surface;
- and
- at least one auxiliary plate disposed between the antenna body and the ground surface,
- wherein the at least one auxiliary plate comprises (i) a support portion connected to and projecting away from the ground surface, the support portion disposed away from the first end of the antenna body length and proximate to a second end of the antenna body length, and (ii) a planar portion connected to and projecting away from the support portion and toward the feed line, the planar portion being substantially parallel to the ground surface.
