Problems solved by technology

[0003] However, the biggest challenge of the narrow-section multi-system antenna is that the distance between the two columns of the linear array layout is too small, so that the coupling is too large and the radiation index is extremely deteriorated, which restricts the application and promotion of the narrow-section multi-system antenna

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0031] It should be noted that when an element is referred to as being "fixed on", "disposed on", "fixed on" or "installed on" another element, it can be directly on the other element or there can also be an intervening element . When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. Furthermore, when one element is considered to be "fixed transmission connection" to another element, the two can be fixed in a detachable connection, or can b...

Abstract

The invention discloses a narrow-cross section multi-system integrated antenna and a low-frequency radiation unit. The low-frequency radiation unit comprises a base, a balun structure, a dipole and aparasitic structure, wherein the balun structure is arranged on the base, the dipole is connected with the balun structure and is arranged above the base through the balun structure, the parasitic structure comprises a dielectric member and a parasitic loading member, and the parasitic loading member is arranged above the dipole through the dielectric member. The low-frequency radiation unit has good isolation, and improves the gain. According to the invention, with the application of the low-frequency radiation unit in a nested antenna and a narrow-cross section multi-system integrated antenna, mutual coupling can be reduced, beam narrowing is facilitated, directivity is improved, and radiation performance is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a narrow-section multi-system antenna and a low-frequency radiation unit. Background technique [0002] With the development of mobile communication, the standards of communication network are also increasing. Due to the limited resources of the base station site, multi-system antennas are integrated on one radome. That is, the antennas of more than three antennas are integrated into a single-antenna antenna or a double-antenna antenna, but this will increase the windward area of ​​the multi-system antenna, which increases the difficulty and cost of the construction and installation of the base station tower, and also increases Requirements for the reliability of the antenna itself and the pole on which the antenna is installed. The narrow-section (≤380mm) wide-beam MSI antenna provides an effective solution to site installation difficulties and high costs, and is very co...
