In this article, a novel beam shaping technique is developed to synthesize the array factor (AF) radiation pattern of linear and planar antenna arrays. The proposed method is established based on the ...

Abandoned coal mines had left waterways acidic and rusty orange. Local residents are cleaning them up, and recovering valuable minerals in the process.

Beamforming in series-fed antenna arrays can inherently suffer from beam-squinting. To overcome the beam-squinting problem, low-dispersion, fast-wave transmission lines can be employed. Such ...
