Ultra wideband planar printed volcano antenna
First Claim
1. An ultra wideband planar printed volcano antenna comprising a printed circuit board with an antenna unit formed on one surface thereof and a grounding unit formed on the opposing surface thereof,wherein the antenna unit includes an electrically conductive radiating element and the rest of the surface of the printed circuit board where the antenna unit is located forms a first electrically nonconductive open area with a first contour formed between the first open area and the radiating element, andthe grounding unit includes an electrically conductive grounding element and the rest of the surface of the printed circuit board, where the grounding unit is located forms a second electrically nonconductive open area with a second contour formed between the second open area and the radiating element and extending upward to the two sides of the printed circuit board without fully enclosing said antenna unit, andwherein the first and the second open areas overlap to each other to have a gradually narrowing adjustable space formed between the radiating element and the grounding element.

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.
