Preliminary Investigations of a Low-Cost Ultrawideband Array Concept

  title={Preliminary Investigations of a Low-Cost Ultrawideband Array Concept},

  journal={IEEE Transactions on Antennas and Propagation},
A design concept is presented that achieves ultra wideband (UWB) array performance with significantly fewer elements than the traditional approach of using a single wideband antenna element type to fully populate the array. Starting from a conventional 8:1 bandwidth array design of a given aperture size, an array of equivalent aperture and bandwidth is created using scaled elements of three different sizes. This wavelength-scaled equivalent array has fewer than 18% of the original element count… CONTINUE READING
