Abstract
Different slot structures have been widely used in numerous designs to produce antennas with enhanced bandwidths. In this paper, a printed slot antenna has been introduced as a candidate for use in the multi-band wireless communication applications. The antenna slot structure has a rectangular shape with its width, from the side of feed, has been modified in the form of Koch fractal curve of the second iteration. The antenna has been fed with 50Ohm microstrip transmission line etched on the reverse side of the substrate. Modeling and performance evaluation of the proposed antenna design have been carried out using a method of moments
based EM simulator, IE3D. Simulation results show that the resulting antenna exhibits a multi-resonant behavior making it suitable for a wide variety of multi-band wireless communication applications. The first resonant band, centered at 2.58 GHz, extends from 2.40 to 2.89 GHz. This band covers the 2.4 GHz WLAN band (frequency range 2.4{2.483 GHz) and the 2.5 GHz mobile WiMAX operating band (frequency range 2.5{2.7 GHz). The second resonant band, centered at 4.03 GHz, extends from 3.40 to 4.50 GHz. This band covers the 3.5 GHz mobile WiMAX operating band (frequency range 3.4{3.6 GHz). While the third resonant band centered at 5.74 GHz, extends from 5.42 to 6.18 GHz. This band covers the U-NII mid-band (frequency range 5.47- 5.725 GHz) and U-NII high-band (frequency range 5.725{5.875 GHz). Parametric study has been carried out to explore the effect of varying the antenna feed line length on its performance.
