Abstract
A dual band inverted-F antenna includes a first antenna element having a first leg connected to a ground plane and a second leg extending along a length from the first leg to a distal end of the second leg. A second antenna element connects to the second leg at a first connection point that is proximal of the distal end of the second leg, the second antenna element electrically coupled to an antenna signal trace of a PCB. A third antenna element is spaced from the second leg of the first antenna element by a gap and positioned along the length of the second leg proximal of the distal end of the second leg but distal of the first connection point. A trap is operatively coupled across the gap between the second leg of the first antenna element and the third antenna element.
