Abstract
We will discuss a small novel hexagonal shaped geometry for ultra wideband (UWB) monopole antenna with notch characteristics. The self-similar nature of this fractal like geometry provides higher effective antenna length and wide operating bandwidth because of the onset of multiple resonances. Notch characteristics are introduced using a rectangular slot in the ground plane, which enhances the reflection coefficient over the entire UWB frequency operating range for the proposed device. The optimized 19 mm × 15 mm dimensions, for the proposed antenna are the smallest among such geometries, exhibiting a large bandwidth from 3.1 GHz to 11.7 GHz with VSWR <; 2 over the entire frequency range. The proposed antenna demonstrates nearly omnidirectional radiation pattern, proper impedance matching, and good return loss over the entire UWB frequency range.
