Broadband planar inverted F antenna

A planar inverted F 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 the second planar surface of said radiating element being substantially coplanar with the first planar surface of said ground plane;
• a first connecting line coupled to an edge of said ground plan and to an edge of said radiating element;
• and
• a second connecting line coupled to the edge of said radiating element on either side of where the first connecting line is coupled thereto.

A planar inverted F antenna, comprising:

• a ground plane having a first planar surface, a first circumference and a first plurality of edges on the first circumference;
• a radiating element having a second planar surface, a second circumference and a second plurality of edges on the second circumference, the second planar surface of said radiating element being substantially coplanar with the first planar surface of said ground plane;
• a first connecting line coupled to a first edge of the first plurality of edges and a first edge of the second plurality of edges;
• and
• a second connecting line coupled to the first edge of the second plurality of edges on either side of the first connecting line.

A method of fabricating a wide bandwidth planar inverted F antenna, comprising the steps of:

• forming a ground plane on a first planar surface;
• forming a radiating element on a second planar surface, wherein the second planar surface is substantially coplanar with the first planar surface;
• coupling a first connecting line to a first edge of the ground plane and to a second edge of the radiating element at a first contact location;
• and
• coupling a second connecting line to the second edge of the radiating element at second and third contact locations.

• 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, and first and second connecting lines are adapted to couple to a radio at a desired impedance.
