Problems solved by technology
[0003] However, due to the limited size of the antenna array of the base station, when the antenna element spacing is reduced, the spatial distribution of antenna elements in different frequency bands often overlaps and nests, and the coupling between antenna elements will significantly affect the performance of the antenna array.
The radiator of the large-sized low-frequency antenna element located above will block the radiator of the small-sized high-frequency antenna element below (such as figure 1 As shown), in this way, when the radiator of the high-frequency antenna element is working, the radiator of the low-frequency antenna element will induce high-frequency current, and the resulting electromagnetic field scattering and reflection will cause the radiation pattern of the high-frequency antenna element to be distorted, thereby Deteriorating the radiation efficiency of the entire multi-frequency common-aperture antenna array

Embodiment Construction
[0064] The following will describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them.
[0065] Antenna array: In order to be suitable for various occasions, two or more single antennas working at the same frequency are fed and arranged in space according to certain requirements to form an array, also called an antenna array.
[0066] Antenna Front: The area of the antenna array.
[0067] Antenna vibrator: The antenna vibrator is the most basic unit of the antenna, which has the function of guiding and amplifying electromagnetic waves. Usually, the antenna vibrator is a conductor. When an alternating current flows on the antenna vibrator, electromagnetic wave radiation can occur, and the radiation capability is related to the structure of the antenna vibrator. In the embodiments of the pre...

Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a multi-band fusion antenna assembly. Background technique [0002] With the advanced development of wireless communication, multiple frequency bands in the second / third / fourth / fifth generation (2G / 3G / 4G / 5G) mobile communication technology will coexist in the base station antenna system. From the perspective of product development and system installation, in order to save valuable space resources, reduce installation difficulty, and improve the compatibility and versatility of the communication system, antennas of different frequency bands are fused together and integrated into a multi-frequency common-aperture antenna array. It is an inevitable trend in the development of base station antennas. [0003] However, due to the limited size of the base station antenna array, when the antenna element spacing is reduced, the spatial distribution of antenna element...
