Novel rugby-ball UWB antenna for base band transmission

In this research we present analysis and measurement results of a new ultra wide band (UWB) antenna. The rugby-ball shaped antenna is fed by the 50 /spl Omega/ coaxial cable through an image ground plane and backed by a reflector for the radiation and detection of ultra-short electric pulses. Maximum pulse amplitude occurs at an elevation angle of 60/spl deg/ for broadside radiation. The antenna has an ultra wideband VSWR performance and 'percent bandwidth' of 198%. The antenna is simple to fabricate and low cost as well.
