A wide band omni directional antenna, in which the radiation parameters are automatically correspond to the frequency of the emitted signal. It can be made by printing and used in small size transducers, for example in cellular telephones. The antenna radiator is formed as an electrically conductive plate, the electrically conductive plate which has a shape of a non-rectangular triangle having two lateral sides of different lengths with first ends of the lateral sides connected with one another in a point connectable to an electric signal source and other opposite second ends, and the electrically conductive plate also has a side which is opposite to the point connectable to the electric signal source and connects the opposite second ends of the lateral sides with each other thus forming a third side of the triangle of the non-rectangular triangle. The antenna can be built by using two joined triangles.
