Antenna network with directive radiation

An antenna network with directive radiation, adapted to operate in at least one predetermined frequency band, comprising:

• at least one pair of metal antennas formed of a first metal antenna and a second metal antenna,
• a monopole antenna having a central position in the antenna network,
• said metal antennas and said monopole antenna being arranged on a ground plane and coupled to each other,
• a load circuit, each metal antenna and the monopole antenna being connected to the load circuit and fed with an electric current by the load circuit, the load circuit being composed of passive components of a capacitive, inductive or resistive nature, or of a combination of these components,
• when fed by the load circuit, each metal antenna emits electric transverse radiation modes and magnetic transverse radiation modes,
• when fed by the load circuit, the monopole antenna emits a magnetic transverse mode radiation TM10
• wherein
• the second metal antenna being sequentially rotated by a predetermined angle of rotation relative to the first metal antenna, an electric transverse radiation mode emitted by the first metal antenna is cancelled by the electric transverse radiation mode emitted by the second metal antenna;
• the load circuit elements are parameterized to provide amplitude and phases of the radiation in which the monopole antenna and the at least one pair of antennas have a destructive interference in a magnetic transverse radiation mode of the at least one pair of antennas, so that the magnetic transverse radiation mode TM10 of the monopole antenna cancels the magnetic transverse radiation mode of the at least one pair of antennas,
• and therefore the at least one pair of metal antennas is configured for a radiation of selected circular polarization.
