<P>PROBLEM TO BE SOLVED: To provide a compact multi-beam antenna system which at least relaxes conventional constraints associated with the size. <P>SOLUTION: A system of multi-beam antennas comprises M radiating sources and P networks, each of the networks including N radiating elements, P being greater than 1 and N being an even number, the radiating elements of the networks being connected two by two via transmission lines of the same electrical length. In addition, the P networks are located to have a common center of the networks, and the M radiating sources are each positioned at a distance Li from the center, the distance Li being strictly less than the distance of the field called the far field and i varying from 1 to M. This system can be used with MIMO type devices. <P>COPYRIGHT: (C)2012,JPO&INPIT |
