Device for receiving and/or emitting signals with radiation diversity

摘要

The present invention relates to a device for receiving and/or emitting signals comprising at least two means for receiving and/or emitting electromagnetic waves of the slot antenna type (10, 11) and means for connecting the said receiving and/or emitting means to means for exploiting the signals, the means for receiving and/or emitting electromagnetic waves being symmetric with respect to a point, and the connection means consisting of supply lines (12, 13) coupled electromagnetically to the slots of the slot antennas, which are connected on one side to a common supply line (14) which is in a plane passing through the point of symmetry, and on the other to an electronic component (15, 16) enabling a short circuit or an open circuit to be simulated at the end of one of the lines and an open circuit or a short circuit to be simulated at the end of the other line. The invention is applicable to wireless networks. <IMAGE>
