Embodiment Construction

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

[0026] For the situation shown in Figure 1, in order to keep the pattern orientation of each element in the array consistent with or close to the expected main beam orientation of the array pattern pattern, the pattern of the array element 1 should face the local normal direction n of the surface where it is located 1 The right side of the scan at a certain angle, adopt the state "R"; the pattern of the array element 2 should be reconstructed in the local normal direction n of the surface where it is located 2 The direction of the state "N" is adopted; the direction diagram of the array element 3 should face the local normal direction n of the surface where it is located 3 Scan the left side at an angle, adopting state "L".

[0027] Similarly, in Figure 2, in order to make the orientation of each element in the array consistent wi...

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...
