Claim:
1. A radiating phase-shifting cell comprising: a plurality of conducting elements formed on a surface of a substrate, above and separated from a ground plane and situated on a periphery, each conducting element being positioned symmetrically around and connected to at least one central conducting element and to neighbouring conducting elements on the periphery by controlled variable capacitive loads, the conducting elements being separated by radially-oriented slots, an arrangement of the slots forming an equivalent resonator whose electrical shape configures a phase-shift applied to a wave to be reflected, wherein the radiating phase-shifting cell comprises the controlled variable capacitive loads, which are capable of varying at least one of an electrical length and of an electrical width of the slots, wherein the conducting elements and the controlled variable capacitive loads are arranged so that, according to at least a first configuration of the controlled variable capacitive loads, a surface conductor of microwave signals is formed to create a resonator that is predominantly inductive, and so that, according to at least a second configuration, the slots are formed around the at least one central conducting element to create a resonator that is predominantly capacitive, and a conducting surface formed by the plurality of conducting elements arranged around the at least one central conducting element and being separated from each other by the slots to not completely encircle the at least one central conducting element.
