Ultra wide band antenna

An antenna comprising:

• a dielectric substrate having first and second sides opposing each other;
• a first conductive pattern formed on the first side of the dielectric substrate forming an asymmetrical monopole with a single order fractal signal feed, the first conductive pattern being a five-sided polygon formed by combining first and second rectangles and an isosceles right triangle, the first rectangle having first and second shorter sides with lengths within 65% of the lengths of first and second longer sides, the first longer side of the first rectangle adjacent a first leg of the isosceles right triangle, the isosceles right triangle having a hypotenuse extending from a first corner formed by the first shorter side and the first longer side of the first rectangle to a second corner of the second rectangle, a second leg of the isosceles right triangle adjacent a first longer side of the second rectangle, with one of two shorter sides of the second rectangle adjacent the first longer side of the first rectangle and co-linear and contiguous with the first leg of the isosceles right triangle, and a second longer side of the second rectangle being co-linear and contiguous with the second shorter side of the first rectangle;
• and
• a second conductive pattern formed on the second side of the dielectric substrate, forming a ground plane under the single order fractal signal feed.
