Summary:
This paper proposes an omni-directional UWB antenna pattern in azimuth cut, low voltage standing wave ratio (VSWR), and easy to construct antenna for ultra wideband (UWB) systems. The designed antenna uses the multi circular blade configuration with a radiating element and a square ground plane. The multi-circular blades UWB antenna suitable for IEEE 802.15.3a and IEEE 802.16 UWB communication applications at 3.1-10.6 GHz and 2-11 GHz bands is presented. This paper discusses the phenomenon of dispersal in UWB antennas and presents a simple design to evaluate the radiated fields from antennas structures. Measured results exhibits extend return loss bandwidth and lower omni-directional pattern deviation in azimuth cut. The antenna design allows a quick assessment of dispersion in design. The proposed multi-circular blades UWB structures is capable of achieving broadband and omni-direction at azimuth cut characteristics within 2~11GHz for UWB wireless communication applications.
