A super wideband antenna

A super wideband radiator (SWB) with the simplest topology and architecture is proposed. The superb results and EM characteristics are recorded by this radiator: 1) the widest bandwidth, to the author knowledge, ever reported from 5GHz till 150GHz, 2) no pattern deformation attested in decade-bandwidth, 3) the smallest form-factor ever achieved. SWB prototype is designed, fabricated and evaluated. Good agreement between numerical predictions and measurements is observed. Performances of the prototypes are thoroughly tested and evaluated.
