    Multi-beam antenna for a mobile telephone base station basically comprising: a two-dimensional array of radiating elements (2) having double polarization, the radiating elements (2) being grouped in arrays (3a, 3b, ..) one-dimensional or multi-dimensional, being both the different arrays (3a, 3b, ...) of radiating elements (2) and the distribution networks completely independent of each other, with the vertical and horizontal beam widths of each array of radiating elements being personalized and optimized independently of the rest of beams so that each distribution network or phase shifter (5) has movable parts that vary the phase provided to the radiating elements (2), allowing to dynamically vary the azimuth angle of each array (3a, 3b, ..) completely independently.

    DESCRIPTION OF A PREFERRED EMBODIMENT. In view of the aforementioned figures and in accordance with the numbering adopted we can observe how a multi-beam antenna for mobile phone base station is described, whose

    In contrast, one-dimensional arrays can be selected that have an approximate vertical beam width of 60 degrees, or arrays with three or more radiating elements in the vertical direction, further decreasing the beam width but increasing the complexity and size of the antenna. Two radiating elements in the vertical direction is the best compromise solution between beam width and antenna dimension. In the practical case of the present invention of five beams with gains greater than 20dBi per beam in the band of 1710-2690MHz, the antenna has affordable dimensions of 1100 x 1300mm (Figure 10). The vertical beam width of 30 degrees also has the advantage of giving very good coverage to a whole tier of a football stadium without the need to offer electric tilt, thus simplifying the overall antenna scheme. However, the antenna can be installed with mechanical tilt if desired without degrading the radiation pattern thanks to the wide vertical beam width.
    A third practical execution is shown in Figure 11, where two three-dimensional arrays 3a and 3e have been added that give coverage to the ends of the cell with lower population density, thus expanding the coverage area without adding complexity to the antenna. The advantage of this embodiment with respect to that shown in Figure 7 is the decrease in dimensions of the coastal antenna to extend wider vertical beam width of the extreme beams.
    With the foregoing explanations the reader can infer multiple possible combinations of implementation subject to the present invention.
    Figure 12a shows a diagram of the mechanism with which the multi-beam antenna object of this invention has been provided for the remote adjustment of the azimuthal pointing direction of each of the beams that make up the antenna. As a general rule, the mechanism is composed of an electronic module 9 and of so many mechanical actuation modules 8a, 8b, .. 8e as phase shifters 5a, .. 5e are present in the antenna, five in the practical embodiment at hand.
    Figure 12b shows a schematic of the way in which the mechanical drive module is coupled to the phase shifters to enable dynamic adjustment of the main beam direction.
    To make possible the azimuthal pointing variation of each of the radiation beams, it is necessary to vary the phase of the signal that is provided to each of the elements of
    12
    image10
    The connection between the electronic module 9 and each of the drive modules is made through cables 50i that carry the motor rotation signals plus the sensors necessary for motion / stop detection.
    In the practical embodiment of this invention, the means for azimuth adjustment have been arranged as an integrated system to the antenna, where both electronic module and mechanical drive systems and motors are within the same radome that surrounds the antenna. However, both internal and external can be arranged without assuming any novelty to what is presented in this invention.
    10 The azimuth adjustment mechanism is designed to be operated manually as well as remotely, as tilt adjustment systems are currently known.
    The azimuth adjustment mechanism includes an indicator 14 visible from the outside that indicates the azimuth configured for each beam.
    In the present invention, this need is met by proposing a multi-beam antenna embodiment with dynamically configurable azimuthal pointing directions and reduced beam widths, while maintaining the general performance for
    20 base station antennas, such as isolation between polarizations and between 30dB beams.
    With all this, an optimal sectorization of the cell is achieved for mass events such as concerts or sports stadiums.
