Abstract
The present invention relates to a device for receiving/transmitting electromagnetic waves with omnidirectional radiation of the type comprising: a first set (100a, 100b, 100c, 100d) of means for receiving/transmitting waves with longitudinal radiation of the printed antenna type, the said means being arranged in order to receive a wide azimuthal sector and at least a second means (104) for receiving/transmitting waves with transverse radiation of the printed antenna type, the second means having radiation complementary to the radiation of the first means, and means (103) capable of connecting in emission the said first and second wave receiving/transmitting means. The invention is especially applicable to domestic networks.
