The combined antenna 100 of the synthetic beam of the present application connects the first antenna 21 and the second antenna 22 together by using a power divider 23, and the first antenna 21 and the second antenna 22 form a certain angle, so that a parallel straight beam and a tilted forward beam can be formed respectively, and a bidirectional coverage beam can be synthesized, and the coverage area is wider. Moreover, the first antenna 21 and the second antenna 22 share a set of signal processing equipment, which is conducive to reducing the number of signal equipment, achieving lightweight, reducing costs, and can be better applicable to the requirements of lightweight and low cost of unmanned aerial vehicles.

[0026] Specifically, Figure 3 As shown, the first fixing plate 11 includes a first substrate 111 and a first mounting plate 112, one side of the first mounting plate 112 is connected to the first substrate 111, and the second fixing plate 12 includes a second substrate 121 and a second mounting plate 122, one side of the second substrate 121 is connected to the first substrate 111, one side of the second mounting plate 122 is connected to the second substrate 121, and the second mounting plate 122 is arranged at an angle to the first mounting plate 112.

Therefore, the specific value of the angle between the first mounting plate 112 and the second mounting plate 122 is not specifically limited here.

[0027] In this embodiment, the first substrate 111 and the first mounting plate 112 are integrally formed by bending.

After the angle is adjusted to the desired angle, the first locking nut 141 and the second locking nut 161 are locked again, so that the adjustment is more convenient. Preferably, the circumferential edges of the first locking nut 141 and the second locking nut 161 are provided with raised wings (not marked in the figure).

In this embodiment, the number of first vibrators 212 and the second vibrators 222 are both three, and the three first vibrators 212 are evenly spaced on the first reflecting plate 211, and the three second vibrators 222 are evenly spaced on the second reflecting plate 221.
