A printed bi-polarization antenna and corresponding network of antennas. The antenna can be used as a probe in a device for testing an antenna by measurement of radio wave radiation, or in the field of telecommunications, for example, in the base stations of a radio communications system, or in a multi-media satellite receiver. The antenna comprises: (a) first, second and third superimposed substrate plates; (b) a first metal deposit situated on the external face of the first substrate pla te defining at least one first radiating element of the dipole type, in the for m of a T, the horizontal bar of the T constituting two radiating lateral strands separated by a coupling slit; (c) a first power supply line pursuant to a first polarization, situated between the first and second substrate plates and supplying power to the at least one first radiating element; (d) a second metal deposit, situated on the external face of a third substrate plate and defini ng at least one second radiating element of the dipole type, in the form of a T , the horizontal bar of the T constituting two radiating lateral strands separated by a coupling slit; and (e) a second power supply line pursuant to a second polarization, situated between said second and third substrate plates and supplying power to the at least one secondradiating element. The antenna limits the dangers of parasitic couplings, has low volume, easy mechanical maintenance, an omni-directional radiation diagram and a broad band width. A corresponding network of the antennas is also described.
