Abstract
A reconfigurable antenna, includes an emissive region, including at least one radiating source designed to emit electromagnetic waves; and an electromagnetic lens, including a set of phase-shifting cells, including switches configured to introduce a phase shift to the electromagnetic waves, and bias lines to bias the switches. The antenna further includes an electromagnetic coupling region, arranged between the emissive region and the electromagnetic lens in order to generate electromagnetic coupling between the electromagnetic waves and the set of phase-shifting cells, wherein the electromagnetic coupling region comprises a set of electrically conductive elements, arranged to form a contour of a resonant cavity guiding the electromagnetic waves towards the electromagnetic lens, the set of electrically conductive elements comprising first tracks electrically connected to the bias lines.
