This paper presents the design of a ultra-wideband monopole antenna based on fractal geometry. The proposed antenna is essentially composed of a hexagonal patch fed by a coplanar waveguide (CPW) Feed. To improve the characteristics of this antenna, trapezoidal shaped elements are added on his sides. This monopole fractal antenna is designed on RO4350B substrate having dielectric constant εr=3.66,...
This paper presents the design and analysis of a new fractal antenna that provides Ultra-wideband characteristics. The Fractal technique is adopted to improve the radiation characteristics of the antenna. First, the proposed antenna is designed on FR4 substrate with dielectric constant εr = 4.4 and thickness h = 1 mm with inicial diameter of solid circular disc 5 mm. Five iterations are applied on...
