ABSTRACT:
An ultra wideband planar printed volcano antenna, which not only complies with the UWB bandwidth standard (3.1 GHz˜10.6 GHz) but also is lightweight, compact, inexpensive, easy to manufacture, high performance, and highly integrated. The ultra wideband planar printed volcano antenna has an antenna unit and a grounding unit formed on one or two printed circuit board by means of etching. The antenna unit includes an electrically conductive radiating element. The rest of the printed circuit board forms an electrically nonconductive open area. The grounding unit has at least one electrically conductive grounding element. The rest of the printed circuit board also forms an electrically nonconductive open area. The overlapping of the two open areas of the printed circuit board forms the adjustable space which has a gradually narrowing shape. By adjusting the size of the adjustable space, the antenna may acquire a best frequency range.
