Abstract
The present invention relates to a device for transmitting and/or receiving electromagnetic waves comprising at least one radiating element for radiating a circular polarization of given sense, characterized in that it comprises at least one means dimensioned and positioned with respect to the radiating element in such a way as to radiate, at the frequency of the radiating element, a circular polarization of opposite sense to that of the radiating element so as to compensate for the cross component of the radiating element. The invention applies more particularly to printed antennas operating under circular polarization.
Claims7
Device for transmitting and/or receiving electromagnetic waves comprising at least one printed-type antenna for radiating a circular or linear polarization of given sense, said polarization presenting a cross component, comprising at least one passive means dimensioned and positioned with respect to the printed-type antenna in such a way as to radiate, at the frequency of the printed-type antenna, a circular or linear polarization of opposite sense to that of the printed-type antenna and whose phase is adjusted so as to compensate for the cross component of the printed-type antenna.
