A tunable dual band notch on a UWB printed slot monopole antenna by using open circuit stubs

A new printed wide slot antenna with single- and dual-band notch behavior is presented. The base of antenna is a simple fork-shaped radiating patch, which covers the ultra-wideband (UWB) frequency range. By using additional protrudent open circuit stubs on the base patch, multiband notch behavior is obtained. Effects of varying the added stubs parameters on the antenna performance show that the center frequency of band rejections can be finely tuned. The proposed dual-band notch antenna covers 2.4–10 GHz with two bands rejection for WiMAX (3.3–3.9 GHz) and WLAN (5.7–6 GHz) bands. © 2011 Wiley Periodicals, Inc.
