Summary:
In recent years, wireless communications have progressed very rapidly. In order to provide with large bandwidth for any wireless application, wideband antenna design has become very important. In the reported literature [1-2], some of CPW-fed and microstrip-line-fed wide-slot antennas have been proposed for the wideband operation. The impedance bandwidths of the wide-slot designs [1-2] can reach about 15~88%. However, they are still not enough for wireless applications. For other reports in [3-5], some of slot antennas for WiMAX applications are proposed. However, the wideband technique used in these designs makes the antenna design more complicated. In this paper, a CPW-fed rhombus slot antenna is proposed for WiMAX applications. Good impedance matching for a wideband operation can be obtained. Within this wide operating impedance bandwidth, the same polarization plane and broadside radiation patterns can be excited.
