Abstract :
In this paper a novel miniaturized ultra-wideband antenna is presented. Using a new fractal-like geometry, dimensions of the antenna are reduced by more than 50%. The proposed fractal-like geometry is implemented on a microstrip-fed planar circular disk monopole antenna. A 10dB return loss bandwidth of final design is 9.58GHz that covers the frequency range of 2.57 to 12.15GHz, having satisfactory radiation properties and good gain. By increasing the iteration number of fractal-like structure, the lower-edge frequency for VSWR of 2 and the first resonant frequency may further be decreased.
