A Low-Cost, mmWave Tileable Sliced Notch Vivaldi Array

In this paper, a design for a low-cost, tileable Sliced Notched Vivaldi Array operating over the mmWave frequency region of 13-50 GHz will be presented. This array is capable of being scanned to ±45° in E and H plane with better than 2:1 VSWR performance. Experimental measurements of the radiation pattern, antenna input impedance, connector and line loss per inch will be presented.
