Abstract
In this paper a compact Koch fractal based printed monopole antenna has been introduced as a candidate for use in applications in which the WiBro, WiMax, ISM and UWB services are integrated. The monopole radiating element has a rectangular shape with two slots cut from each corner. In addition, the sides of the radiator, except that of the feed line direction, have been modified to be in the form of Koch fractal curve of third iteration. A small rectangular slot has been made in the ground plane beneath the feed line. The antenna has been fed with an offset 50 Ohm microstrip transmission line. Both the antenna and the feed line have been printed on an FR-4 substrate with a thickness of 1.59 mm and relative permittivity of 4.4. Modeling and performance evaluation of the proposed antenna have been carried out using a method of finite integration technique (FIT) based EM simulator, CST Microwave Studio. Simulation results show that the proposed antenna offers an impedance bandwidth, for return loss ≤ –10 dB in the range of 2.3 – 11.5 GHz. Furthermore, the proposed antenna radiating element has a compact size of 20 × 20 mm2.
