Abstract
A multi-band antenna includes a non-conductive pane, a ground plane disposed on the non-conductive pane, and a radiating strip for operating in a plurality of frequency bands. The radiating strip includes an elongated portion and a meander line portion extending away from an end of the elongated portion. The radiating strip also includes a pair of tuning stubs extending from the elongated portion.
Claims14
A multi-band antenna comprising:
- a ground plane formed of conductive material;
- a radiating strip formed of conductive material and disposed generally co-planar with said ground plane;
- said radiating strip including an elongated portion having a proximal end adjacent said ground plane and a distal end terminating in a meander line portion opposite said proximal end of said elongated portion;
- a first tuning stub extending from a first point on said elongated portion between said proximal end and said distal end;
- and
- a second tuning stub extending from a second point on said elongated portion between said proximal end and said distal end.
