Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The conventional double-frequency dual-polarized antenna unit scheme on the market is basically that two single-frequency dual-polarized antenna units are designed, and the rethread filter is combined, but the design mode is complex, the materials are more, the labor cost for assembling the working procedures is high, the comprehensive cost is high, the production efficiency is low, and the three-order intermodulation indexes of the antenna are easily subjected to multi-section assembling to generate a lot of unstable and uncertain conditions.
Therefore, the inventor proposes a frequency division coplanar design, which can directly design two single-frequency single-polarization antenna oscillators on a dielectric plate in a coplanar manner, specifically, as shown in fig. 2, a high-frequency oscillator arm 21 'and a low-frequency oscillator arm 22' formed on one surface of the dielectric plate are distributed on the left side and the right side, and are arranged at intervals up and down, and the other surface is designed as a mirror image. The design has the advantages of simple structure, few components and easy assembly, can abandon the conventional filter combiner and can realize the frequency division effect, but the design has more obvious defects, the effective frequency bandwidth is narrower, the broadband and the ultra-broadband effects cannot be achieved, the expanded width of the oscillator arm of the scheme is wider, and the standing-wave ratio cannot be optimized to meet the target of being less than or equal to 1.5.
In order to solve the problem, the inventor provides a 5G ultra-wideband antenna unit based on a frequency division coplanar flag-shaped oscillator technology and a V-shaped frequency balance slot technology through a large number of research and design.
Specifically, as shown in fig. 3-5, the 5G ultra-wideband antenna unit includes a dielectric plate 1 with two sides coated with copper, and the flag oscillators 2 and 3 formed on the two sides of the dielectric plate 1 by a copper coating technique and being mirror images of each other are formed on the dielectric plate 1. Each flag- shaped oscillator 2 and 3 is formed by 1/4 lambda oscillator lengths of at least two different 5G frequencies through frequency division coplanar design, wherein lambda is the wavelength corresponding to the 5G frequency, namely, unlike the prior art, oscillators with different frequencies are formed on independent units and then combined; furthermore, each of the flag- shaped oscillators 2, 3 is obliquely arranged relative to the central axis of the dielectric slab, and a V-shaped frequency balance groove 4 is formed between adjacent edges of the flag-shaped oscillators on two sides in a overlooking state and under a perspective condition of the dielectric slab, so that the electric length of the oscillator arm spacing of the flag- shaped oscillators 2, 3 on two sides is gradually changed from the starting frequency of the antenna unit to the ending frequency of the antenna unit.
Through the design, the frequency division coplanar flag-shaped oscillator technology is utilized to prevent the current of the antenna unit from generating jump on a plane due to unbalance on a fluid path of the oscillator due to the superposition effect, so that the aim of balancing the fluctuation amplitude of the resistance and the reactance of the antenna unit is fulfilled; the V-shaped frequency balance groove technology is utilized to enable the electric length of the distance between the oscillator arms to be gradually changed from the initial frequency of the antenna unit to the final frequency of the antenna unit so as to balance the problem of inconsistency of the electric length distances between the oscillator arms with different frequencies, and meanwhile, the problems of sudden change of current distribution of the antenna and low performance of the antenna unit caused by frequency hopping and reflection of the antenna unit are solved. The 5G ultra-wideband antenna unit not only meets the network communication frequency band of 2G and 4G network systems, but also meets the frequency band use requirement of a 5G (fifth generation mobile communication) network system, and simultaneously abandons the conventional filter combination, and has the advantages of less materials, small volume, ultra-wideband, low cost, simple structure, easiness in mass purchasing, production and manufacturing and the like.
The following is a detailed description of two 5G frequencies, but it is understood that the invention is not limited thereto. The two 5G frequencies are 1710-.
As shown in fig. 3 to 5, the present embodiment provides a 5G ultra-wideband antenna unit 100, which includes: the dielectric plate comprises a dielectric plate 1, and a first flag-shaped vibrator 2 and a second flag-shaped vibrator 3 which are respectively formed on the front surface 11 and the back surface 12 of the dielectric plate 1, wherein the first flag-shaped vibrator 2 and the second flag-shaped vibrator 3 are mirror images relative to a central axis 13 under the perspective of the dielectric plate 1.
The first flag-shaped oscillator 2 comprises a coplanar high-frequency oscillator arm 21 and a coplanar low-frequency oscillator arm 22 which are connected up and down, specifically, the low-frequency oscillator arm 22 and the high-frequency oscillator arm 21 are respectively designed into an arc flag-shaped structure according to 1/4 lambda oscillator lengths L1 and L2 of 1710-. It should be noted that the operating wavelengths corresponding to different 5G frequencies are different. Different 5G frequencies on the flag-shaped vibrators are arranged in a row from high to low, specifically, on the first flag-shaped vibrator 2, the ground-to-ground distance h1 of the high-frequency vibrator arm 21 is 1/4 lambda and is arranged below the flag-shaped structure, the ground-to-ground distance h2 of the low-frequency vibrator arm 22 is 1/4 lambda and is arranged above the flag-shaped structure, and then the Printed Circuit Board (PCB) is used for coplanar printing on a plane, wherein lambda is the wavelength corresponding to the 5G frequency. In the concrete implementation, the surface area of the oscillator arm is determined according to the effective resonant impedance of the preset 5G frequency and the length of the oscillator. The flag structure is not limited to the circular arc shape, and may be provided as another polygon (as shown in fig. 6), and the requirements of the length of the vibrator, the ground clearance, and the surface area may be satisfied.
It should be noted that, since the second flag oscillator 3 and the first flag oscillator 2 are mirror images of each other, the structure of the second flag oscillator 3 is not described herein again. By the design, the first flag-shaped oscillator 2 and the second flag-shaped oscillator 3 are formed by utilizing the frequency-division coplanar design, and the mirror surfaces of the first flag-shaped oscillator and the second flag-shaped oscillator are arranged on two sides of the dielectric plate 1, so that the current of the antenna unit 100 cannot generate jump on one plane due to unbalance caused by the superposition effect in the fluid path of the oscillator arm, and the purpose of balancing the fluctuation amplitude of the resistance and the reactance of the antenna unit 100 is achieved.
As shown in fig. 7, the pitch 4' of the conventional oscillator arms is designed to be a fixed pitch, and the conventional fixed pitch can only take an intermediate value to adapt to the preset frequency, but the bandwidth performance cannot achieve the design effect of broadband and frequency division after the design. The inventor of the invention proves through a large amount of experiments that the first flag-shaped oscillator 2 and the second flag-shaped oscillator 3 are respectively arranged obliquely relative to the central axis 13 of the dielectric plate 1 and are inclined towards the direction far away from each other, specifically, under the overlooking state and the perspective condition of the dielectric plate 1, a V-shaped frequency balance groove 4 is formed between the adjacent edges of the first flag-shaped oscillator 2 and the second flag-shaped oscillator 3 at the two sides, as shown in figure 3, by such design, the upper part of each flag-shaped oscillator is an oscillator arm with lower frequency, the lower part of each flag-shaped oscillator is an oscillator arm with higher frequency, and the two sections of frequencies belong to wide frequency, the problem of asynchronous interval of the oscillator arms with different frequency wavelengths can be well compatible through the design of the V-shaped groove, so that the electric length of the oscillator arms of the first flag-shaped oscillator 2 and the second flag-shaped oscillator 3 is gradually changed from the initial frequency of the antenna unit 100 to the termination frequency of the antenna unit 100, the inconsistency of the distance electrical lengths of the oscillator arms with different frequencies is balanced, the current distribution of the antenna is prevented from suddenly changing, and the problem of low performance of the antenna unit 100 caused by frequency hopping and reflection of the antenna unit 100 is solved. In specific implementation, the inclination angle can be adjusted according to the 5G frequency and the design of resonant impedance.
A trapezoidal balanced balun 5 is further formed on the front surface 11 of the dielectric plate 1 and connected with the first flag-shaped oscillator 2 on the same side. The requirement of ultra-wideband required by the design of the present invention cannot be met by the symmetrical feed balun of the conventional antenna element 100 according to the frequency design requirement. The inventor skillfully arranges the feed balun on one side of the dielectric plate 1 and optimally designs the feed balun into a trapezoidal balance balun 5, so that unit current can be uniformly and smoothly guided to the oscillator arms (the low-frequency oscillator arm 22 and the high-frequency oscillator arm 21) to carry out high-performance radiation.
For impedance matching, an impedance conversion section 6 is further formed on the back surface 12 of the dielectric board 1, and is connected to the lower portion of the flag-shaped oscillator on the same side, that is, is connected to the connection line 7.
Further, an outer conductor welding hole 9 is formed in the trapezoidal balance balun 5 and used for welding an outer conductor of a cable so as to connect the trapezoidal balance balun 5 with the outer conductor of the cable. An inner conductor welding position 10 is arranged at the tail end of the connecting wire 7 of the second flag-shaped oscillator 3 positioned on the other side (namely the back 12 of the dielectric plate 1), and a cable inner conductor penetrates through the cable outer conductor welding hole 9 to be connected with the inner conductor welding position 10 and is used for connecting the second flag-shaped oscillator 3 on the different side from the trapezoidal balance balun with the cable inner conductor.
The 5G ultra-wideband antenna unit 100 further includes a ground welding site 8, which is connected to the trapezoidal balanced balun 5.
As shown in fig. 8 and 9, the 5G ultra-wideband antenna unit 100 of this embodiment has the following advantages:
(1) in the figure 8, the standing wave ratio in the frequency band of 1710 MHz-2700/3300-3800 MHz is not more than 1.5, and the better frequency division effect is achieved, so that the good low reflection requirement is met.
(2) The device has the advantages of less materials, small size, ultra-wide band, low cost, simple structure, easy mass purchase, production and manufacture and the like;
(3) when the method is used for signal coverage, the method is compatible with the use requirements of 2G, 3G and 4G communication frequency bands and can meet the requirements of a 5G frequency network.
It can be seen from fig. 9 that the half-power lobe widths of the horizontal plane and the vertical plane are uniform within the frequency band, and the amplitude of different frequency points is not large due to the ultra-wideband; the antenna has good signal concentration and directional radiation characteristics.
From comparison of fig. 10 and the graph, it can be found that the bandwidth of the product in the conventional technology (the scheme shown in fig. 7) is obviously insufficient, and the broadband and frequency division effect cannot be achieved under the same standing-wave ratio requirement, and the product design target cannot be reached.
The invention also provides a 5G ultra-wideband antenna, which comprises a metal reflecting plate 200 and a pair of 5G ultra-wideband antenna units 100, wherein the pair of 5G ultra-wideband antenna units 100 are vertically arranged on the metal reflecting plate 200; two 5G ultra-wideband antenna units 100 are orthogonally arranged, for example, one 5G ultra-wideband antenna unit 100 is transversely inserted into the metal reflection plate 200, and the other 5G ultra-wideband antenna unit 100 is longitudinally inserted into the metal reflection plate 200 to form a vertical and horizontal polarization embodiment, as shown in fig. 11, and for example, one 5G ultra-wideband antenna unit 100 is inserted into the metal reflection plate 200 along the transverse left side and is upwardly inclined by 45 degrees, and the other 5G ultra-wideband antenna unit 100 is inserted into the metal reflection plate 200 along the transverse right side and is upwardly inclined by 45 degrees, to form a ± 45 ° polarization embodiment, as shown in fig. 12, but not limited thereto.
