Abstract

La présente invention concerne un système d'antennes destiné à être monté sur ou au-dessus d'un objet tout en protégeant ledit objet des rayonnements desdites antennes. Selon la présente invention, il est constitué d'au moins un groupe (21, 22; 100) d'au moins deux antennes, les antennes (221, 222, 223 ; 111, 112, 113) étant positionnées l'une par rapport à une autre de manière que leurs lobes d'émission tournés vers l'espace E où se trouve ledit objet se chevauchent, lesdites antennes étant alimentées de manière que les champs électromagnétiques respectivement émis dans lesdits lobes d'émission tournés vers ledit espace E interfèrent les uns avec les autres et de manière que l'énergie du champ électromagnétique résultant de ces interférences soit diminuée dans ledit espace E comparée à ce qu'elle serait sans interférence.The present invention relates to an antenna system intended to be mounted on or above an object while protecting said object from radiation from said antennas. According to the present invention, it consists of at least one group (21, 22; 100) of at least two antennas, the antennas (221, 222, 223; 111, 112, 113) being positioned relative to one another. to another so that their emission lobes facing towards the space E where said object is located overlap, said antennas being supplied so that the electromagnetic fields respectively emitted in said emission lobes facing towards said space E interfere with the with each other and so that the energy of the electromagnetic field resulting from such interference is reduced in said space E compared to what it would be without interference.
