Abstract :
In this paper, CPW-fed slot antennas using loading metallic strips and a widened tuning stub on a finite size reflector that prevents the back radiation and provides the unidirectional radiation are investigated. The dependence of return losses and radiation patterns on the CPW-fed slot to finite reflector size spacing is presented. The IE3D is used for evaluating the antenna characteristics that are divided into two cases: the first case with different reflector sizes and the second case with different reflector distances. The proposed antennas can be used in GSM1800, GSM1900, PCS, IMT-2000 and WLAN applications
