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.

Compact resonant cavity antenna

The treatment device () is capable of cooperating with an elongate element () provided with a plurality of electronic chips () staggered along the length of the elongate element (). This treatment device () has a housing () with an input orifice () and an output orifice () for the elongate element (), and a treatment cavity () arranged between the input orifice () and the output orifice () and provided with a treatment probe () for electronic chip. Furthermore, the treatment device comprises an isolation system () configured to isolate an electronic chip to be treated present in the cavity () from other electronic chips of the plurality of electronic chips arranged outside of the cavity ().
