A compact slot antenna with CPW-fed for IEEE 802.16-2004 applications

In this paper, a wideband slot antenna with coplanar waveguide (CPW) fed for IEEE Std 802.16-2004 applications is presented. By introducing the sunk ground plane, the narrow feeding-line, and the beveled inner-conductor, the required impedance bandwidth is achieved over the frequency range from 2.15 to 5.83 GHz (S11 < -10 dB). This proposed antenna with broadband bandwidth and small size can be suitable for communication products of wireless local area network (WLAN) or WiMax applications.
