A phase shifter module (CD), dedicated to a reflectarray antenna, is defined by a characteristic resonant length and, in at least one chosen place, has an MEMS type device (DC, DC') able to be placed in at least two different states respectively permitting and prohibiting the establishing of a short-circuit intended to vary said resonant length, in order to vary the phase shifting of a wave to be reflected presenting at least one linear polarization.

Phase shifter module whose linear polarization and resonant length are varied by means of MEMS switches

The present invention relates to a dielectric resonator antenna comprising a block () of dielectric material of which a first face intended to be mounted on an earth plane is covered with a metallic layer (). According to the invention, at least one second face perpendicular to the first face is covered with a partial metallic layer () having a width less than the width of this second face. The invention applies in particular to DRA antennas for domestic wireless networks.

The present invention relates to a wideband antenna consisting of a dielectric resonator or DRA mounted on a substrate with an earth plane. The resonator is positioned at a distance x from at least one of the edges of the earth plane, x being chosen such that 0&#x2266;x&#x2266;&#x3bb;/2, with &#x3bb;/2 the wavelength defined an the dielectric of the resonator. This invention applies to wireless networks.
