Abstract

In this paper a simple rectangular monopole antenna with variable band-notched function is proposed. The antenna is constructed on a FR4-epoxy substrate by thickness of 1.6mm and ε_r=4.4. The proposed antenna shows Ultra-Wideband (UWB) characteristics from around 3 up to 10.6GHz for VSWR<; 2. Two shorting pins running through the substrate connect the patch to the inverted L-shaped stubs printed on the bottom of the substrate to create multi-filtering function. By changing the stubs´ lengths the proposed antenna shows variable single and double filtering characteristics.
