On the design of tree-type ultra wideband fractal Antenna for DS-CDMA system

This article describes the CPW-feed ultra wideband tree type monopole fractal antenna and it’s backscattering. The prototype antenna is fabricated with optimized dimension. The experimental result of this antenna exhibits the ultra wideband characteristics from 5.0 GHz to 14.0 GHz. The experimental and simulated results are in good agreement. The effects of various design parameters on impedance bandwidth have also been studied in detail using EM simulator. The nature of H and E - plane radiation patterns are omni-directional and bidirectional respectively. The measured group delay is almost...
