Description

Technical Field

[0001] This invention belongs to the field of antenna technology and relates to a cooperatively reconfigurable antenna with wide-angle multi-beam scanning. Background Technology

[0002] With the development of new-generation information technology, wireless communication and sensing have entered the intelligent era. However, intelligent communication and sensing applications place higher demands on the performance and functionality of antennas. Multi-beam scanning antennas, due to their flexible beam switching and wide-angle multi-beam radiation coverage, can effectively improve channel capacity and enhance anti-interference capabilities, thus serving as a new antenna option for intelligent wireless and sensing applications.

[0003] Currently, multi-beam scanning antennas can be broadly categorized by their technical implementation into phased arrays, antennas based on multi-beamforming networks, and reconfigurable antennas. Existing phased arrays typically utilize numerous T / R components and phase shifter chips to control the phase and amplitude of each element, thereby achieving flexible beam scanning and beamforming. However, existing phased arrays require a large number of expensive T / R components, resulting in inherent drawbacks such as high cost and system complexity, making them unsuitable for large-scale, low-cost wireless communication applications. Antennas based on multi-beamforming networks typically use a multi-beamforming network to feed and excite each antenna element, achieving multi-beam switching scanning by switching different feed ports. Common technologies include Butler matrices and Noren matrices. However, existing multi-beamforming network-based antennas, due to limitations in phase shift range and state, typically only achieve simple beam switching and a narrow beam scanning range. Furthermore, multi-beamforming networks usually require additional space for deployment, resulting in technical bottlenecks such as large size and complex structure, making them unsuitable for miniaturized applications. Reconfigurable antennas typically employ RF switching devices such as PIN diodes and varactors to control the field distribution (radiating aperture distribution) on the antenna surface. The switching of the RF switches then enables beam reconfiguration and multi-beam scanning coverage. However, most existing reconfigurable antennas are based on single-antenna aperture designs, thus limited by the size of the radiating aperture, resulting in low gain and a limited number of beam reconfiguration states, making it difficult to meet the demands of long-distance wireless communication applications.

[0004] As can be seen from the above review and analysis of existing technologies, existing multi-beam scanning antennas still have disadvantages and problems such as high cost, large size, and limited beam scanning range. Therefore, existing multi-beam scanning antennas are difficult to meet the ultimate demands of intelligent communication and detection applications. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 This application provides a wide-angle multi-beam scanning cooperative reconfigurable antenna, including: at least two digital coding reconfiguration units 10; the digital coding reconfiguration unit includes: a dielectric resonator 101, a metal ground plane 102, a microstrip feed line 103, a 1-bit phase-tuned feed structure 104, a 90° phase-shift structure 105, and a switchable parasitic monopole stub 106.

[0021] In terms of connection, the metal ground plane 102 is positioned below the dielectric resonator 101, and the microstrip feed line 103 is positioned on the back of the metal ground plane 102; the 1-bit phase-tuned feed structure 104 is positioned in the middle of the dielectric resonator 101; the 90° phase-shift structure 105 is positioned on the microstrip feed line 103, and the 1-bit phase-tuned feed structure 104 and the 90° phase-shift structure 105 are cascaded; switchable parasitic monopole stubs 106 are positioned on both sides of the 1-bit phase-tuned feed structure. For the connection relationships of each part, please refer to... Figure 2 The three views shown are shown.

[0022] Among them, the dielectric resonator 101 can excite TE 01δ The dielectric resonator 101 is used as a carrier for generating electromagnetic waves. The material of the dielectric resonator 101 can be a high dielectric constant and low loss medium, specifically alumina ceramic, cerium oxide ceramic, dielectric substrate, etc. The shape of the dielectric resonator 101 can be a prism, prismatic, sphere, etc., and this application does not limit it.

[0023] The metal ground plane 102 is located below the dielectric resonator 101 and serves as the reference ground plane for the radiator. It is used for directional beam generation. The metal ground plane 102 can be made of metal surfaces such as copper, aluminum, or tin, and its shape can be a square, circle, or other planar shape.

[0024] The microstrip feed line 103 is disposed on the back of the metal floor 102 and serves as the feed excitation for the radiator.

[0025] A 1-bit phase-tuned feed structure 104 is disposed in the middle of the dielectric resonator 101, and is in the form of a U-shaped coupled slot feed structure.

[0026] A 90° phase shift structure 105 is disposed on the microstrip feed line 103, and is in the form of a multi-path phase shift structure with an added radio frequency switch.

[0027] Among them, the 1-bit phase-tuned feed structure 104 and the 90° phase-shift structure 105 are used for phase encoding reconstruction and digital representation, such as using digital 0 and 1 for combined representation, to construct the array factor digital encoding.

[0028] The dielectric resonator 101 and the switchable parasitic monopole stub 106 are used for pattern coding reconstruction and digital representation, such as using a combination of digital 0 and 1 to construct unit factor digital coding.

[0029] In summary, the wide-angle multi-beam scanning cooperative reconfigurable antenna provided in this application proposes a digital coding reconstruction unit 10 with phase and pattern coding reconstruction. This unit achieves independent reconstruction of the radiation phase and radiation pattern with only a small number of RF switches (low complexity), thus improving beam reconstruction capability from two degrees of freedom: array factor control and element factor control. Furthermore, by introducing the principle of digital coding reconstruction, the phase and pattern are represented by 0 / 1 digital representations, enabling multifunctional beam switching and wide-angle multi-beam scanning while maintaining miniaturization, low complexity, and low cost. The wide-angle multi-beam scanning cooperative reconfigurable antenna provided in this application can meet the extreme demands of intelligent communication and detection applications.

[0030] Optionally, the 1-bit phase tuning feed structure 104 is used to generate 0° and 180° phase reconstruction switching, and the 90° phase shift structure 105 is used to generate 0° and 90° phase reconstruction switching.

[0031] Specifically, for phase encoding reconstruction, the digital encoding reconstruction unit 10 has 2-bit phase encoding capability, consisting of a cascaded 1-bit phase tuning feed structure 104 and a 90° phase shift structure 105. The 1-bit phase tuning feed structure 104 generates 0° and 180° phase switching, while the 90° phase shift structure 105 generates a reconfigurable 90° phase shift component. By combining the 1-bit phase component and the 90° phase shift component, the digital encoding reconstruction unit 10 achieves 2-bit phase encoding reconstruction, namely 0° (“00”), 90° (“01”), 180° (“10”), and 270° (“11”). 00, 01, 10, and 11 correspond to different encoding reconstruction phases.

[0032] Optionally, when both the switchable parasitic monopole stub 106 on the left and the switchable parasitic monopole stub 106 on the right are disconnected, the dielectric resonator 101 operates at TE. 01δ The mode radiates a side-emitting pattern; when the switchable parasitic monopole stub 106 on the left is turned on and the switchable parasitic monopole stub 106 on the right is turned off, the TE of the dielectric resonator 101... 01δ The mode and the left monopole submode combine to radiate a radiation pattern deflected to the left; when the switchable parasitic monopole stub 106 on the right is turned on and the switchable parasitic monopole stub 106 on the left is turned off, the TE of the dielectric resonator 101... 01δ The pattern and the single-level sub-pattern on the right combine to radiate a directional pattern that deflects to the right.

[0033] Specifically, the pattern encoding reconstruction consists of a dielectric resonator 101 and switchable parasitic monopole stubs 106 on both sides; the dielectric resonator 101 excites the TE... 01δ The mode produces a toroidal electric field distribution and radiates a side-emitting pattern, which can be equivalently regarded as an odd mode. The switchable parasitic monopole stub 106 introduces monopole components, produces a symmetrical electric field distribution, and radiates an omnidirectional pattern, which can be equivalently regarded as an even mode.

[0034] When switchable monopole stubs are loaded on both sides of the digital encoding reconstruction unit 10, the digital encoding reconstruction unit 10 will construct switchable parity mode responses, thereby realizing encoding reconstruction of different orientation patterns.

[0035] Specifically, when both switchable parasitic monopole stubs 106 are disconnected, the dielectric resonator 101 only excites TE. 01δ The pattern radiates a side-emitting radiation pattern, introducing the concept of digital encoding, encoded as a "00" state. When the switchable parasitic monopole stub 106 on the left is turned on, the dielectric resonator 101 simultaneously excites TE. 01δThe mode and the left-side monopole mode construct an odd-even mode (multi-mode) response, radiating a radiation pattern deflected to the left, encoded as a "01" state; conversely, when the right-side switchable parasitic monopole stub 106 is turned on, the dielectric resonator 101 simultaneously excites TE. 01δ The mode and the monopole mode on the right construct an odd-even mode response with an antiphase distribution, radiating a radiation pattern deflected to the right, encoded as a "10" state; by combining the above radiation pattern states, the digital encoding reconstruction unit 10 realizes multi-state radiation pattern encoding reconstruction.

[0036] In summary, by integrating phase-shifting and multi-mode structures, the digital encoding and reconstruction unit 10 reconstructs the digital codes of the phase and radiation pattern, i.e., the digital encoding and reconstruction of the array factor and element factor. Specifically, Figure 3 This demonstrates the phase reconstruction performance of the digital encoding reconstruction unit 10. Figure 4 The performance of the radiation pattern reconstruction corresponding to the digital encoding reconstruction unit 10 is shown.

[0037] like Figure 3 As shown, the digital encoding and reconstruction unit 10 implements 2-bit phase encoding and reconstruction, with a 90° phase shift frequency band covering the 2.20~2.80GHz band, thus fully covering the 2.40GHz band for Wi-Fi wireless applications. Figure 4 As shown, the digital encoding and reconstruction unit 10 implements three different states of radiation pattern encoding and reconstruction: a left-deflecting radiation pattern, a side-firing radiation pattern, and a right-deflecting radiation pattern. Figure 3 and Figure 4 It can be seen that the digital encoding reconstruction unit 10 realizes 2-bit phase encoding reconstruction and 3-state pattern encoding reconstruction.

[0038] Optionally, a digital encoding reconstruction unit 10 is constructed by co-constructing matrix factors and unit factors.

[0039] Specifically, such as Figure 5 As shown, the cooperative reconfigurable antenna consists of multiple digitally encoded reconfigurable units 10. The radiation pattern and phase are encoded and reconstructed using 0 / 1 digital reconfiguration signals, thereby achieving the control of unit factors and array factors. Finally, through the cooperative reconfiguration of array factors and unit factors, the array achieves wide-angle multi-beam scanning functionality.

[0040] In other words, this application proposes a wide-angle multi-beam scanning cooperative reconfigurable antenna. Utilizing a cooperative reconfiguration mechanism of array factors and element factors, the phase (array factor) and radiation pattern (element factor) of each digitally coded reconfigurable element 10 are jointly controlled, thereby achieving wide-angle multi-beam reconfiguration scanning. In other words, this application employs digitally coded reconfigurable elements 10 for phase and radiation patterns, enabling the cooperative reconfigurable antenna to jointly manipulate array factors (phase-coded reconfiguration) and element factors (radiation pattern-coded reconfiguration), thus possessing greater radiation control freedom and achieving wide-angle multi-beam scanning reconfiguration. Specifically, by introducing an element radiation pattern control dimension, a cooperative reconfiguration mechanism of array factors and element factors (more degrees of freedom) is constructed, achieving wide-angle multi-beam reconfiguration under the premise of low cost and miniaturization (using only a small number of elements / array components).

[0041] Please continue reading. Figure 1 Optionally, the digital encoding reconstruction unit 10 further includes a DIP switch 107.

[0042] The DIP switch 107 is located on the back of the metal base plate 102 and is used to control the on and off states of the radio frequency switching device.

[0043] That is, the DIP switch 107 is arranged in the rear area of ​​the digital encoding reconstruction unit 10 and is located on the back of the metal floor 102. It is used to control the on and off states of devices such as PIN diodes (RF switching devices), that is, to control the phase and pattern reconstruction states.

[0044] Of course, the digital encoding reconstruction unit 10 can also be a controller such as a microcontroller / FPGA.

[0045] Optionally, the digital encoding reconstruction unit 10 further includes a DC bias line and a light-emitting diode 108.

[0046] A DC bias line and a light-emitting diode 108 are disposed on the back of a metal ground plane for connecting to drive radio frequency switching devices (such as PIN diodes) and for displaying the on and off states of the radio frequency switching devices.

[0047] Optionally, the digital encoding reconstruction unit 10 also includes a nylon screw 109.

[0048] Nylon screws 109 are disposed around the dielectric resonator 103 and penetrate the metal ground plane 102 to fix and support the cooperative reconfigurable antenna.

[0049] Please see Figure 6 and Figure 7 Optionally, embodiments of this application provide a cooperative reconfigurable antenna 100, wherein at least two digital encoding reconfiguration units 10 are arranged and extended using a one-dimensional linear array.

[0050] Optionally, the number of digital encoding reconstruction units 10 is 4.

[0051] Of course, in other embodiments, the number of digital encoding reconstruction units 10 can also be 3, 6, etc. At least two digital encoding reconstruction units 10 can also be flexibly extended to a two-dimensional form, a circular array form, etc., which is not limited in this application.

[0052] Optionally, the cooperative reconfigurable antenna 100 also includes a microstrip feed port 20 and a microstrip feed power divider 30.

[0053] The microstrip power supply port 20 is connected to the microstrip power divider 30, and the microstrip power divider 30 is connected to the microstrip power supply line 103 of the digital encoding and reconfiguration unit 10.

[0054] A microstrip feed port 20, located at the edge of the metal ground plane 102, connects to an external RF channel and is used to excite the cooperative reconfigurable antenna. A microstrip feed power divider 30 is located on the back of the metal ground plane 102 and is used for power distribution in the feed network. By combining the microstrip feed port 20 and the microstrip feed power divider 30, a multi-channel microstrip feed network is constructed to provide equal-amplitude and in-phase feeding excitation to each digital coding reconfiguration unit 10.

[0055] Specifically, such as Figure 6 As shown, when there are four digital encoding and reconfiguration units 10, the microstrip feed port 20 and the microstrip feed power divider 30 construct a four-way equal-amplitude, in-phase microstrip feed network, which is used to power and excite the four digital encoding and reconfiguration units 10. At this time, the DIP switch 107, the DC bias line, and the light-emitting diode 108 construct a 24-way DC bias circuit, which is used to encode and reconstruct the radiation phase and pattern state of the four digital encoding and reconfiguration units 10. Then, the array factor and the element factor can be manipulated simultaneously to flexibly switch the pattern of each digital encoding and reconfiguration unit 10 in different beam scanning areas, thereby achieving high-gain and low-sidelobe beams in different scanning areas. Through joint reconstruction using the array factor and the element factor, the cooperative reconfigurable antenna 100 not only obtains more switchable beams but also achieves a wider beam scanning range.

[0056] It should be noted that, Figure 6 For a device description of the digital encoding reconstruction unit 10, please refer to the description in the foregoing embodiments, which will not be repeated here.

[0057] Please refer to the experimental data. Figure 8 and Figure 9 , Figure 8 and Figure 9 These represent the surface electric field distribution and radiation beam of the cooperative reconfigurable antenna 100 under different digital phase and pattern encoding states.

[0058] Depend on Figure 8 It can be seen that under different digital phase and digital pattern coding conditions, the cooperative reconfigurable antenna 100 excites different surface electric field distributions, and the radiation aperture of the cooperative reconfigurable antenna is digitally characterized, thereby realizing radiation aperture distributions with different directions.

[0059] (a) Beam pointing θ = -60°; (b) Beam pointing θ = -30°; (c) Beam pointing θ = -10°; (d) Beam pointing θ = 0°; (e) Beam pointing θ = +10°; (f) Beam pointing θ = +30°; (g) Beam pointing θ = +60° like Figure 9 As shown, by digitally encoding the phase and radiation pattern of each digital encoding reconstruction unit 10, the radiation aperture of the cooperative reconfigurable antenna 100 is digitally characterized, thereby realizing multi-beam switching and wide-angle beam scanning. Thanks to the contribution of joint manipulation of array factor and unit factor, the cooperative reconfigurable antenna achieves ±60° wide-angle multi-beam reconstruction scanning with only 4 digital encoding reconstruction units 10 (miniaturization and low cost). (a) Beam pointing θ = -60°; (b) Beam pointing θ = -30°; (c) Beam pointing θ = -10°; (d) Beam pointing θ = 0°; (e) Beam pointing θ = +10°; (f) Beam pointing θ =+30°; (g) Beam pointing θ = +60° In summary, the conceptual process of this application is as follows: introducing radio frequency switch control technology, digital encoding reconstruction principle, and array factor & unit factor collaborative reconstruction mechanism.

[0060] First, a novel phase and pattern digitally encoded radiation element / array element is proposed.

[0061] Next, multiple digital coding units are arranged in an array to form a digitally reconfigurable array antenna design.

[0062] Finally, based on the array factor and unit factor collaborative reconstruction mechanism, wide-angle multi-beam reconstruction scanning was achieved by adjusting the digital phase and pattern state of each unit to match intelligent communication and detection applications.

[0063] Furthermore, the wide-angle multi-beam scanning cooperative reconfigurable antenna of this application has the following beneficial effects: This invention proposes a phase and radiation pattern digital coding reconstruction unit based on radio frequency switch control technology and multi-mode radiation modulation mechanism. This unit achieves independent reconstruction of the radiation phase and radiation pattern using only a small number of radio frequency switches (low complexity). Furthermore, the digital coding reconstruction principle is introduced to perform 0 / 1 digital representation of the phase and radiation pattern, providing unit support for subsequent collaborative reconfigurable array antenna design.

[0064] Based on the array factor and unit factor collaborative reconstruction mechanism and digital coding reconstruction unit, this invention proposes a collaboratively reconfigurable antenna 100. By reconstructing the phase and radiation pattern of each unit using 0 / 1 coding, beam control is performed from two degrees of freedom: array factor (unit phase) and unit factor (unit radiation pattern), thereby achieving flexible beam switching and wide-angle multi-beam scanning.

[0065] In this invention, compared to existing reconfigurable antennas, the digitally coded reconfiguration unit 10 achieves coordinated reconfiguration of array factors and unit factors, improving beam reconfiguration capability from two degrees of freedom. With only a small number of units (miniaturization and low cost), the coordinated reconfigurable antenna 100 of this invention achieves flexible multi-beam switching and large-angle beam scanning, making it suitable for large-scale wireless deployment applications.

[0066] In this invention, based on radio frequency switch control technology, digital coding reconstruction principle and array factor and unit factor collaborative reconstruction mechanism, a collaborative reconfigurable antenna scheme is proposed for the first time, realizing wide-angle multi-beam reconstruction scanning, while taking into account miniaturization, low complexity and low cost.
