| ABSTRACT |
An omni-directional antenna comprising a ground plane; a vertical plate, bearing a conducting strip, disposed between the board and the ground plane; a feed point located at a point on the board ; and a prularity of radiating elements of at least two sizes affixed on the board , wherein the radiating elements from different iterations changes a current path on the board and creating different resonant frequencies at the same time. The radiating elements affixed on the board are made of an arrat of square.
