<p>A low cost array with wide band elements interleaved into an 'egg-crate' structure. The radiating elements are flared notch radiators. Good impedance match over a wide band was achieved by feeding each element with a tapered quasi-TEM slot line, which transforms a 50-ohm input impedance to a 120-ohm radiation impedance. The radiating elements are fed by a true time delay beamforming network.</p> |
