Dipole antenna oscillator

Abstract

The present invention discloses a dipole antenna oscillator. The dipole antenna oscillator comprises a power distribution member provided with a plurality of power distribution blocks; and a pluralityof radiation racks arranged at the circumference side of the power distribution member, each radiation rack comprises two coupling arms arranged at intervals and respectively provided with electricalconnection ends connected with the adjacent power distribution blocks, first and second isolation gaps are formed between the two coupling arms, the portion from the electrical connection ends to theextension ends of the coupling arms forms a current path with a quarter wave length, a half wave length or a full wave length corresponding to a first isolation gap tail end to allow the length of the current path formed at the second isolation gap tail end to be larger than the length of the current path formed at the first isolation gap tail end; the two adjacently arranged radiation racks arerespectively provided with the coupling arms, the coupling arms and the power distribution member are electrically connected with the corresponding same power distribution block to commonly constructand form the radiation member.

Problems solved by technology

[0002] In the early days when the industry designed dual-polarized dipole antennas, most of them used two crossed feeders as the conductor connection interface fed into the coaxial line, and adjusted the matching value by changing the length and width of the feeders; Or, there is also a design in the industry that another section of conductive frame is connected to the end of the coaxial line as the feed-in structure of the dipole antenna; this design not only needs to increase the disadvantages of additional assembly cost and material cost, but also because of the assembly process The problem of electrical difference caused by instability

[0003] In view of the above-mentioned problems, some improvements have been proposed in the relevant industries, such as making the radiation frame of each unit at the upper end of the support frame consist of two coupling arms with an angle configuration relationship, and adjacent to the coupling arms of the radiation frame. There is an interval configuration relationship between them; this kind of dipole antenna dipole shape is still found in practical application experience, because after the two coupling arms with an angle configuration relationship in each unit radiation frame are formed, the surface between the two coupling arms Flattening accuracy is prone to bending and deformation deviations. As a result, the corresponding relationship between the coupling arms adjacent to the radiation frame after its assembly is relatively easy to cause excessive deviations and affect performance. This is really worthy of concern. Important technical issues for the industry to think about breakthroughs
