Problems solved by technology

However, due to the complex structure and many parameters of the sleeve, it is difficult to take into account both good matching characteristics and frequency bandwidth
Moreover, in the process of actually making the antenna, the structural size of the antenna needs to be limited by the processing conditions, which restricts the working bandwidth of the antenna to a certain extent.
[0004] Based on the shortcomings of existing sleeve antennas such as complex structure, difficult parameter adjustment, and limited processing, this invention proposes a deformed sleeve antenna structure

[0044] figure 1 It is a structural schematic diagram of a 4-column deformed sleeve antenna according to the present invention. The antenna includes a bottom-loaded conductor column 1, a conductive base plate 7, and an internal conductor column 4 of the antenna. The deformed sleeve antenna of the 4 columns adopts a deformed sleeve conductor column array 3 evenly arranged on the outer edge of the rectangular conductive base plate 7 to replace the traditional sleeve.

Abstract

Disclose is a small-sized multi-frequency-band deformation sleeve antenna. The sleeve structure of the existing sleeve antenna is simplified into multiple column bodies uniformly arranged on a bottom plate; matching of antenna input impedance is realized by loading metal columns at the bottom; by virtue of such design, the same radiation characteristic as the conventional sleeve antenna is maintained while the processing difficulty of the antenna is greatly lowered; and in addition, the deformation sleeve antenna is also additionally provided with a spiral conductor structure, and corresponding electrical dimensions of the working frequency band of the antenna are provided by the spiral structure, so that the overall physical length of the deformation sleeve antenna is shortened. The invention further provides a high-frequency radiation structure which can be coupled with the deformation sleeve structure; by matching with the deformation sleeve structure, the radiation bandwidth of the antenna can be expanded effectively; and the deformation sleeve antenna provided by the invention is symmetrical in structure, simple and concise, convenient for product processing and realization, and convenient to install, so that the mechanical strength of the antenna body can be effectively improved.

Description

technical field [0001] The invention relates to the field of wireless communication hardware design, in particular to a multi-frequency broadband sleeve antenna. Background technique [0002] With the rapid development of wireless communication systems, the original traditional narrowband antennas can no longer meet the needs of continuously developing wireless communication systems. At the same time, in order to minimize the interference between antennas, it is necessary to reduce the number of antennas as much as possible. Therefore, in use, multiple communication stations usually need to share fewer antennas or even share the same antenna. This also requires that the antennas developed now can cover as many frequency bands as possible while ensuring performance requirements such as high communication efficiency, good matching, low loss, and small size. Considering the research status of the existing antennas and various requirements for antennas in modern wireless commu...
