Abstract
A mono-band or multi-band planar inverted F antenna (PIFA) structure comprises a planar radiating element having a first area, and a ground plane having a second area that is substantially parallel to the radiating element first area. The second area further comprises a section having a meandering form elongating the effective overall length of the radiating element.

An antenna comprising:
- a ground plane having a first planar surface and a first area;
- a radiating element having a second planar surface and a second area, wherein said second planar surface of said radiating element is substantially in parallel with the first planar surface of said ground plane and said second area comprises a section having a meandering form elongating the effective overall length of the radiating element;
- and
- a first connecting line coupled to a first edge of said ground plane and to a second edge of said radiating element at a first contact location;
- and
- a second connecting line coupled to the second edge of said radiating element at second and third contact locations.
