Description

Technical Field

[0001] The invention relates to an all-metal dual-polarization phased array, and in particular to a cylindrical conformal all-metal dual-polarization phased array. Background Art

[0002] Cylindrical conformal dual-polarization phased arrays are becoming an indispensable component of wireless communication networks with their flexible beam scanning capabilities, excellent anti-interference performance and low air resistance. Cylindrical conformal dual-polarization phased array technology is particularly suitable for space-constrained wireless communication and radar systems. Cylindrical conformal dual-polarization phased arrays can be tightly integrated with the carrier surface and can operate effectively in confined environments. In long-distance wireless communications, high-gain cylindrical conformal dual-polarization phased arrays are an effective solution to overcome path loss. Specifically, cylindrical conformal dual-polarization phased arrays with high gain characteristics and the ability to maintain low gain fluctuations within a wide-angle scanning range have become very promising candidates in this field. This type of phased array can not only effectively improve signal strength, but also ensure signal stability and quality when receiving signals in multiple directions. Considering the significant advantages of metal structures in low loss, high power capacity and efficient heat dissipation, metal materials have become the first choice for realizing high-gain cylindrical conformal dual-polarization phased arrays. These characteristics enable the cylindrical conformal dual-polarization phased array to maintain high performance in complex and changing application environments while ensuring the long-term reliability of wireless communication and radar systems.

[0003] Usually, in order to obtain a scanning range of ±60°, the period of the antenna unit in the phased array is about 0.5λ H (λ H is the free space wavelength at the highest frequency in the target operating band). This design requirement greatly increases the difficulty of miniaturizing the metal structure, which has a significant impact on the scanning performance of the beam. Although some existing cylindrical conformal dual-polarization phased arrays have excellent broadband characteristics, they still have limitations in beam scanning range and scanning gain fluctuation, and cannot simultaneously take into account the scanning range of ±60° and the gain fluctuation of less than 3.5dB. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a cylindrical conformal all-metal dual-polarization phased array capable of taking into account both wide scanning angle and low gain fluctuation performance.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a cylindrical conformal all-metal dual-polarization phased array, comprising a cylindrical surface, and n×n all-metal single-polarization phased array units with exactly the same structure, where n is an integer greater than or equal to 2; the n×n all-metal single-polarization phased array units are all arranged on the cylindrical surface, and are evenly arranged in n rows and n columns to form an array. If the n all-metal single-polarization phased array units in the kth row are translated by 0.5λ along the row directionH The distance will completely overlap with the k+2th row of n all-metal single-polarization phased array units. If the kth row of n all-metal single-polarization phased array units are first translated by 0.25λ along the row direction H Then rotate 0.52λ around the circumference of the cylinder H The arc length of each all-metal single-polarization phased array unit is finally rotated 90° counterclockwise or clockwise around its center line, and will completely overlap with the n all-metal single-polarization phased array units in the k+1th row, k = 1, 2, ..., n-2, λ H is the free space wavelength at the highest operating frequency of the cylindrical conformal all-metal dual-polarization phased array, the n all-metal single-polarization phased array units in the 2m+1th row are all used to radiate or receive horizontal polarization signals, and the n all-metal single-polarization phased array units in the 2wth row are all used to radiate or receive vertical polarization signals. If n is an odd number, then m=0, 1, ..., (n-1) / 2, w=1, 2, ..., (n-1) / 2; if n is an even number, then m=1, 2, ..., (n-2) / 2, w=1, 2, ..., n / 2; each all-metal single-polarization phased array Each unit includes a feeding part and a radiating part. On the one hand, the feeding part is used to access external signals and transmit the accessed signals to the radiating part. The radiating part is used to radiate the signals transmitted to it by the feeding part into free space. On the other hand, the radiating part is used to receive signals in free space and transmit the signals to the feeding part. The feeding part is used to output the signals. The radiating part is realized by a magnetoelectric dipole and a metal wall. The metal wall is symmetrically loaded on both sides of the magnetoelectric dipole.

[0006] Compared with the prior art, the present invention has the advantages that by using all-metal single-polarization phased array units of the same structure to be arranged in different orientations, the all-metal single-polarization phased array units in different orientations can respectively realize the radiation and reception of horizontal polarization signals and vertical polarization signals, thereby realizing dual polarization by using all-metal single-polarization phased array units with exactly the same structure. In addition, in each all-metal single-polarization phased array unit, the radiation part is realized by loading metal walls on both sides of the magneto-electric dipole, and the magneto-electric dipole realizes the stable narrow beam pattern radiation in the target frequency band. The metal wall is equivalent to a monopole, which radiates a radiation pattern similar to an "8" shape. The narrow beam radiation pattern and the radiation pattern similar to the "8" shape are superimposed, which ensures that the active unit radiation pattern of the cylindrical conformal all-metal dual-polarization phased array has a wide beam width performance. Benefiting from the wide beam active unit radiation pattern having the performance of maintaining low gain fluctuation at a large angle, this supports the cylindrical conformal all-metal dual-polarization phased array to have low gain fluctuation performance during large-angle beam scanning. Therefore, the present invention has both wide scanning angle and low gain fluctuation performance.

On the one hand, the feeding part is used to access external signals and transmit the accessed signals to the radiating part. The radiating part is used to radiate the signals transmitted to it by the feeding part into free space. On the other hand, the radiating part is used to receive signals in free space and transmit the signals to the feeding part. The feeding part is used to output the signals. The radiating part is realized by the magneto-electric dipole and the metal wall. The metal wall is symmetrically loaded on both sides of the magneto-electric dipole.

[0030] In this embodiment, when the cylindrical conformal all-metal dual-polarization phased array is in use, an SMP connector connected to the lower end surface of the first cylinder 6 therein is installed in the card slot 3 of each all-metal single-polarization phased array unit 1 .

[0031] When the cylindrical conformal all-metal dual-polarization phased array realizes the transmitting function, the external transmitting system transmits the signal to the feeding part of each all-metal single-polarization phased array unit 1 through each SMP connector. In each all-metal single-polarization phased array unit 1, first, the signal passes through the coaxial structure composed of the cylindrical hole 4 and the first cylinder 6. At this time, the TEM mode signal is transmitted. Further, the signal is transmitted to the rectangular slot 5 through the first cylindrical 6 structure extending into the rectangular slot 5. A good matching transition of the signal is achieved through the three-level transition structure composed of the second cylinder 7, the first rectangular block 8 and the second rectangular block 9. Subsequently, the signal is transmitted to the double-ridge waveguide structure composed of the third rectangular block 10 and the fourth rectangular block 11. Here, the TE10 mode signal is transmitted. This process completes the stable conversion of the signal from the TEM mode to the TE10 mode. The TE10 mode signal is used to excite the radiation part. The TE10 mode signal is transmitted to the eleventh rectangular block 18 and the twelfth rectangular block 19. At the magnetoelectric dipole composed of the thirteenth rectangular block 20, the fourteenth rectangular block 21, the fifteenth rectangular block 22, the sixteenth rectangular block 23, the seventeenth rectangular block 24, the eighteenth rectangular block 25, the first isosceles right-angled triangle block 26, the second isosceles right-angled triangle block 27, the third isosceles right-angled triangle block 28, the fourth isosceles right-angled triangle block 29, the nineteenth rectangular block 30, the twentieth rectangular block 31, the twenty-first rectangular block 32 and the twenty-second rectangular block 33, a stable directional radiation pattern is achieved. Further, the metal wall composed of the fifth rectangular block 12, the sixth rectangular block 13, the seventh rectangular block 14, the eighth rectangular block 15, the ninth rectangular block 16 and the tenth rectangular block 17 can be equivalent to two monopole structures, which can expand the beam width of the radiation pattern of the all-metal single-polarization phased array unit 1. Thanks to the wide-beam unit radiation pattern, the phased array can maintain low gain fluctuation performance during the ±60° large-angle beam scanning process, and finally the signal is stably radiated into the free space to achieve signal transmission.

[0032] When the cylindrical conformal all-metal dual-polarized phased array realizes the receiving function, each SMP connector is connected to the external receiving system. In each all-metal single-polarized phased array unit 1, after the radiating part receives the signal in the target frequency band in the free space, the metal wall composed of the fifth rectangular block 12, the sixth rectangular block 13, the seventh rectangular block 14, the eighth rectangular block 15, the ninth rectangular block 16 and the tenth rectangular block 17 and the magnetoelectric dipole composed of the eleventh rectangular block 18, the twelfth rectangular block 19, the thirteenth rectangular block 20, the fourteenth rectangular block 21, the fifteenth rectangular block 22, the sixteenth rectangular block 23, the seventeenth rectangular block 24, the eighteenth rectangular block 25, the first isosceles right-angled triangle block 26, the second isosceles right-angled triangle block 27, the third isosceles right-angled triangle block 28, the fourth isosceles right-angled triangle block 29, the nineteenth rectangular block 30, the twentieth rectangular block 31, the twenty-first rectangular block 32 and the twenty-second rectangular block 33 jointly realize the signal reception. At the same time, the nineteenth rectangular block 30, the twentieth rectangular block 31, the twenty-first rectangular block 32 and the twenty-second rectangular block 33 realize good impedance matching transition for the target frequency band signal, and transmit the signal to the double-ridge waveguide structure composed of the third rectangular block 10 and the fourth rectangular block 11 to realize the transmission of TE10 mode signal. At this time, the signal is gradually converted from TE10 mode to TEM mode through the three-level transition structure composed of the second rectangular block 9, the first rectangular block 8 and the second cylinder 7. The TEM mode signal is further transmitted to the first cylinder 6. At this time, the signal is well impedance matched through the coaxial structure composed of the first cylinder 6 and the cylindrical hole 4. The signals within the target working frequency band can be stably transmitted to the feeding part, and further transmitted to the SMP connector through the coaxial structure. Finally, the signal is sent to the back-end receiving system by the SMP connector to realize signal reception.

[0033] In order to verify the performance of the cylindrical conformal all-metal dual-polarization phased array of the present invention, the cylindrical conformal all-metal dual-polarization phased array of the present invention is simulated, wherein the active standing wave simulation diagrams of the cylindrical conformal all-metal dual-polarization phased array of the present invention are shown in Figures 9(a) and 9(b), and the normalized beam scanning direction diagrams of the cylindrical conformal all-metal dual-polarization phased array of the present invention are shown in Figures 10(a), 10(b), 10(c), and 10(d).

[0034] Figure 9 (a) and Figure 9 (b) respectively show the changes in active standing waves when the cylindrical conformal all-metal dual-polarization phased array is scanned along the E-plane direction and the H-plane direction. The three curves in the figure correspond to the active standing waves of the cylindrical conformal all-metal dual-polarization phased array when the beam points to 0°, 30° and 60°. Analysis of Figure 9 (a) and Figure 9 (b) shows that: when the beam pointing does not exceed 60°, the active standing wave of the cylindrical conformal all-metal dual-polarization phased array of the present invention can be guaranteed to be less than 3 within the target operating frequency band of 12-15GHz.

[0035] Figures 10(a) and 10(b) respectively show the beam scanning conditions of the cylindrical conformal all-metal dual-polarization phased array of the present invention along the E-plane direction and the H-plane direction at 12 GHz, and Figures 10(c) and 10(d) respectively show the beam scanning conditions of the cylindrical conformal all-metal dual-polarization phased array of the present invention along the E-plane direction and the H-plane direction at 15 GHz. From the analysis of Figures 10(a), 10(b), 10(c), and 10(d), it can be seen that the cylindrical conformal all-metal dual-polarization phased array of the present invention can achieve a scanning range of ±60° within the target operating frequency band of 12-15 GHz, and has a gain fluctuation of less than 3.5 dB.

[0036] In summary, the cylindrical conformal all-metal dual-polarized phased array of the present invention improves the antenna unit structure and adopts an all-metal single-polarized phased array unit 1 to simultaneously realize horizontal polarization and vertical polarization, thereby achieving a large angle scanning range and having low gain fluctuation performance.
