Abstract
A wireless communication device is described, having an analogue-digital hybrid architecture comprising passive phase shifters. The device includes a control module configured to control means for switching the communication device, such that the device is capable of alternating between three separate modes: a first/second mode in which each passive phase shifter is integrated into a transmission/reception chain, and a third mode in which each passive phase shifter is integrated into a transmission line. The transmission line includes a first portion connecting a first port of the passive phase shifter to the elementary antenna to which it can also be connected in the first/second modes and configured such that substantially all the electromagnetic energy associated with a transmission beam received by the elementary antenna is transmitted to the passive phase shifter, and also includes a second portion connecting the second port of the passive phase shifter to an impedance configured to reflect the electromagnetic energy.
