Among them, the inner conductor of the first high-frequency coaxial cable 83 is welded and electrically connected to the end 752 of the first feeding piece 75, the inner conductor of the second high-frequency coaxial cable 84 is welded and electrically connected to the end 762 of the second feeding piece 76, the outer conductor of the first high-frequency coaxial cable 83 is welded and electrically connected to the first high-frequency feeding hole 711, and the outer conductor of the second high-frequency coaxial cable 84 is welded and electrically connected to the second high-frequency feeding hole 721.

[0070] In the embodiment, the two low-frequency feeding holes (i.e. low-frequency ports) are fed by two coaxial cables, each coaxial cable inputs a circuit signal to a corresponding feeding needle, and each feeding needle inputs the circuit signal to a low-frequency half-wave dipole at a diagonal position through two feeding cables of the same length close to the low-frequency vibrator balun at the diagonal position, so as to excite the two radiation straight arms of the two low-frequency half-wave dipoles at the diagonal position to radiate low-frequency electromagnetic waves, thereby realizing the conversion from the low-frequency circuit signal to the spatial low-frequency electromagnetic waves.

[0071] The two high-frequency feeding holes (i.e. high-frequency ports) are also fed by two coaxial cables, each feeding coaxial cable inputs a circuit signal to a corresponding feeding piece, and each feeding piece inputs the circuit signal to a group of high-frequency single dipoles at a diagonal position, so as to excite the radiation square arm of the high-frequency single dipole to radiate high-frequency electromagnetic waves, thereby realizing the conversion from the high-frequency circuit signal to the spatial high-frequency electromagnetic waves.

[0072] By inputting low-frequency circuit signals and high-frequency circuit signals into the four ports of the above integrated vibrator spotlight antenna device, the low-frequency half-wave dipoles of the integrated vibrator spotlight antenna device are excited to radiate low-frequency electromagnetic waves, and the high-frequency single dipoles are excited to radiate high-frequency electromagnetic waves, thereby realizing the conversion from the low-frequency and high-frequency circuit signals to the spatial low-frequency and high-frequency electromagnetic waves.

[0073] In summary, the utility model integrates four low-frequency half-wave dipoles and four high-frequency single dipoles, and has the advantages of simple structure, small space occupation, convenient assembly, good consistency and high production efficiency; in addition, the reasonable vibrator balun structure design makes the coupling between the high-frequency and low-frequency vibrator baluns small, and the antenna can obtain the advantages of high isolation and high gain.

[0074] The above embodiments only express the preferred embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent range of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, such as combining different features in each embodiment, which all belong to the protection scope of the utility model.
