In this paper, a compact new fractal printed monopole antenna, inspired of Sierpinski gasket, for ultra-wideband (UWB) applications is reported. The proposed antenna is designed by developing a novel mathematical model and a new iterative procedure to generate a fractal geometric shape of the modified Sierpinski gasket (MSG). The recursive procedure to form an MSG as a radiating element is based on an equilateral triangular grid of nodes which is constructed by using a recursive sequence. The MSG radiating monopole is fed by coplanar waveguide (CPW) to achieve a 50 impedance matching with a trapezoidal ground plane. Simulation and optimization of various parameters of the proposed fractal antenna are performed using CST Microwave Studio. The simulated results indicate that the proposed antenna possesses a moderate gain over the entire band with a peak of 4.77 dBi at 9.8 GHz. The stated antenna is also compared with the related literature reviews to differentiate its performance. The total size of the presented antenna is 19×20×1.52 mm3, which is designed on Rogers RO4003C substrate (tan δ = 0.0027 and εr = 3.38). Moreover, a compact prototype is implemented and tested. The measured results of the reflection coefficient characteristics show good agreement with the simulated results. The designed antenna exhibits omnidirectional radiation patterns and covers the frequency range 2.22-10.7 GHz, making it suitable for wireless and UWB applications. |
