Example Embodiment

[0025] Figure 1, Figure 2 and Figure 3 show three specific implementations of the pattern reconfigurable antenna array of the present invention.

[0026] For the situation shown in Figure 1, if the direction of each element in the array is to be consistent or close to the desired main beam direction of the array, the direction of the array element 1 should be directed toward the local normal direction of the curved surface where it is located. 1 Scan at a certain angle on the right side of, and adopt the state "R"; the pattern of array unit 2 should be reconstructed in the local normal direction of the surface where it is located. 2 The direction of, adopts the state "N"; the pattern of the array unit 3 should be towards the local normal direction of the curved surface where it is located. 3 Scan a certain angle on the left side of, adopt the state "L".

[0027] In the same way, in Figure 2, if the direction of each unit in the array is to be consistent or close to the expected ma...

Abstract

This invention relates to double fold tank structure direction pattern to re-form antenna and its array, wherein, the antenna comprises medium base 36, back conductive board 37 an common board 35 with double fold tank and two irradiation arms through co waveguide transmission line with relative switch and detector to realize three status antenna direction scanning through changing detector or switch work status, wherein, the said antenna array uses array unit to distribute onto load curved surface and to keep unit adjacent irradiation direction.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to curved surface array and conformal antenna array technology. Background technique [0002] The side lobe suppression method of the phased array antenna is basically the same as that of the general array antenna. In the case of equal amplitude and same phase, the side lobe level of the antenna array can only reach -13dB in theory, but it is actually higher than this level. In many practical situations, high level sidelobes are undesirable. Because it can generate unwanted interference, especially for radars, causing false echoes. On the other hand, when the radiating elements of the array are conformal to the curved surface, due to the influence of the curvature of the curved surface, the maximum direction of the pattern of each radiating element is different, which brings great difficulties to the pattern design and sidelobe suppression of the array. [0003] T...
