An ultra wideband (UWB) slot antenna is proposed, developed, and experimentally validated in this article. The Norman window‐shaped UWB slot antenna demonstrates stable radiation characteristics in both directions—zenith (θ = 0°) and nadir (θ = 180°) over the entire UWB frequency range (3.1–10.6 GHz...
