Connected arrays of slots and dipoles have become the technology of choice for compact, low profile, wideband and wide scanning antennas. The principle of operation consists in creating a continuous current distribution over the radiating aperture, avoiding resonances and reducing impedance variations at the array elements over very wide frequency and scan ranges.
IETR (Institut d’Électronique et de Télécommunications de Rennes, UMR CNRS 6164) has recently proposed CTS arrays links in the V- and E-bands. In D-band, a connected arrays in polystrata technology has been recently proposed with 4096 radiating elements.
