abstract

  • A new class of ultra-wideband (UWB) fully-planar inverted-L element (FILE) single polarized arrays is introduced. The proposed FILE unit cell (UC) structure achieves the same bandwidth with the conventional FILE single-polarized array but with significantly reduced fabrication complexity and cost. The main distinction lies in the absence of the via fence, while retaining all other essential characteristics, such as unbalanced feeding, ease of manufacturing and assembly. An infinite array operating from 34 GHz to 100 GHz (3: 1) is designed with active VSWR < 3 while scanning up to 45° in the E-, H-, and D-planes.
