Abstract (en)
[origin: EP1580844A1] The phase shifter has a slot radiator (FR) provided with micro electromechanical systems (DC). The systems are to be placed in two different states permitting and prohibiting respectively creation of a short circuit intended to vary a characteristic resonating length of the slot radiator, in order to shift a phase of wave reflected by the phase shifter. An independent claim is also included for a reflectarray antenna comprising a phase shifter.
