A novel ultra-wideband (UWB) array operating from L-band to 40 GHz is presented. The novelty of this design is the simplified fabrication using a hybrid approach that uses i) low-loss Rogers substrate for fabrication of the antenna elements and feed, and ii) 3D printed structure for high-precision assembly. Simulations showed a VSWR < 2.8 at broadside and scanning down to 45° in all planes across the 2 - 40 GHz band. These simulations will be validated through fabrication and measurement of a 15 × 15 array prototype, to be presented at the conference.
