DETAILED DESCRIPTION OF THE INVENTION

(8) An antenna array platform (1) which provides performing the estimation of the direction in a wide frequency band without ambiguity in azimuth and elevation angles, using an antenna array having different antenna distances which are longer than the half of the wavelength, essentially comprises: at least one bottom plate (2), at least one magnet (3) preferably located on the bottom side of the bottom plate (2), which provides the bottom plate (2) to be attached to suitable platforms made of a material that can be attracted by magnetic field force without the need for any mechanical adaptations, at least one box (4) located on the bottom plate (2), at least one lid (5) covering the upper part of the box (4), a number of antenna openings (10) equal to the number of antennas (11) to be used, made in the lid (5) angling holes (7) made in the side of the box (4) so that they correspond to certain angle values, at least one plate (8) that provides support so that the box (4) stays at a required position, at least one screw (9) entering the angling hole (7) positioned at at least one side of the plate (8) and that corresponds to the required angle, providing the plate (8) stays fixed

(9) Thanks to the inventive antenna array platform (1) the estimation of the direction in a wide frequency band without ambiguity in azimuth and elevation angles, using an antenna array having different antenna distances which are longer than the half of the wavelength, can be performed.

(10) In the preferred embodiment of the invention, a bottom plate (2), a box (4) positioned on the bottom plate (2) and antenna openings (10) opened in the antenna hub (6) provided on the lid (5) closing the box (4) are present. In order to estimate the azimuth and elevation angles of the antenna array, taking into account the sizes of antenna elements to be used, accuracy of direction and ambiguity problem during the design phase, antennas are located on the antenna openings (10) at suitable positions so that an ambiguity on a plane is not formed.

(11) Magnets (3) are preferably located on the bottom side of the bottom plate (2), in order for the antenna array platform (1) to be attached to suitable surfaces made of a material that can be attracted by magnetic field force. Thus, no mechanical adaptation processes needed on the platforms used.

(12) An additional lifting mechanism is also used for the antenna array to be able to be positioned on azimuth and elevation angles. This lifting mechanism consists of angling holes (7) opened on the side of the box (4), a plate (8) and a screw (9). Angling holes (7) are present in the side of the box (4), between 0 degrees to 45 degrees with preferably 5 degree intervals, provided that the horizontal of the antenna is assumed 0 degrees. The antenna array can be positioned at a required angle value by means of preferably mace headed screw (9) positioned on at least one side of the plate (8) which is positioned on one side of the box (4), entering the angling holes (7) that corresponds to the required angle.
