Problems solved by technology
At the same time, the radiation polarization of non-planar array elements is not uniform, so it may lead to high cross-polarization
[0005] The (ellipsoid) spherical structure is difficult to process and the cost is high. The design difficulties mainly include the following points: 1. It is difficult to analyze the characteristics of (ellipsoid) spherical conformal antenna elements and the mutual coupling between elements. 2. The conformal It is difficult to synthesize array antenna patterns, 3. Difficult to control the polarization of conformal array antennas, 4. Complex beamforming and control, 5. Difficult to test (calibrate)

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings. The protection scope of the present invention is not limited to the following:
[0019] Such as figure 1 As shown, a conformal antenna mounting skeleton includes a first layer skeleton 1, a second layer skeleton 2 and a third layer skeleton 3. The first layer skeleton 1, the second layer skeleton 2, and the third layer skeleton 3 are in the same ellipsoid surface, and the inclination angle of each layer is different. The first layer skeleton 1 and the second layer skeleton 2 are tangent to the ellipsoid surface, and the third layer skeleton 3 and the second layer skeleton 2 The spherical tangent has a tangent included angle a. Preferably, the tangent included angle a is 10°. In this way, the uniformity of antenna radiation, that is, the gain flatness in the scanning range, can be improved. In the actual process, the first layer of skeleton 1 , The second layer of skeleton ...

Description
Technical field [0001] The invention relates to the technical field of conformal antennas, in particular to a conformal antenna installation skeleton. Background technique [0002] Conformal (ellipsoidal) spherical antenna array can achieve omni-directional radiation on a hemispherical surface. It has incomparable advantages in many antenna systems. It can be used in ground communication systems, airborne and vehicle-mounted mobile communication systems, and can also be used in radar, positioning, and navigation fields. [0003] There are many types of conformal antenna arrays, including conical arrays, spherical arrays, and cylindrical arrays. It has the characteristics of a conventional planar antenna array, but also has many differences. [0004] Planar arrays have been maturely used in many fields, but their scanning angles are generally up to about 60°. The spherical array can cover all directions. This can play a good role in satellite tracking, communications and other fi...
