摘要：The paper presents the designs of two Sierpinski carpet fractal antennas. The fractal properties have been applied in order to designs compact and wideband antennas. The antennas are analyzed in term of radiation parameters such as reflection coefficients, voltage standing wave ratio and radiation patterns. The results shows that the bandwidths of the antennas at the reflection coefficient less than -10dB are 5.5GHz and 7.25GHz ranging from 8.3GHz to 2.8GHz and 4.75GHz to 12GHz respectively. The directivities of antenna are 5.109dBi, 6.952dBi, 6.696dBi and the gains are 5.11dBi, 6.95dBi, and 6.7dBi. The bandwidth is largest at high resonance points with increasing the number of iterations. The proposed designs are suitable for wireless applications such as Wi-Fi, WiMAX, WLAN, Bluetooth, WCDMA and GSM.
