1. A wireless communication device having an architecture configured to emit and receive transmission beams in full-duplex mode via an array of antenna elements and including:
a plurality of passive phase-shifters distributed according to a first set of passive phase-shifters and a second set of passive phase-shifters, each of said plurality of passive phase-shifters including a first port and a second port, the phase shifters of the first set of passive shape shifters and the second set of passive phase-shifters being respectively connected, via their first ports, to power low-noise amplifiers of emission reception chains connected to said antenna elements, each emission/reception chain being associated with a reception/emission chain so as to form a pair of chains,
a junction circuit being arranged between the chains of each pair of chains, and
at least one controlling module configured to control switching means (400) of said device and to activate/deactivate analog and digital interference cancellation means of said device as well as all or part of the emission and reception chains, so that the device is able to alternate between at least two distinct modes:
a first mode in which the cancellation means as well as the emission and reception chains are activated, the passive phase-shifters being connected to their respective chains via their second port, and
a second mode in which the chains, apart from their respective amplifiers, are deactivated, the second port of a passive phase-shifter integrated into a chain of a pair of chains being connected, via the junction circuit associated with said pair, to the second port of the passive phase-shifter integrated into the other chain of said pair.
