Description

Technical Field

[0001] The present invention relates to the technical field of antennas, and in particular, to a computational antenna and a control method based on spatio-temporal digital control signal regulation. Background Art

[0002] As a transducer between guided waves and free space waves, antennas play an indispensable role in various fields. While transmitting and receiving signals, people utilize the designs of parabolic antennas and array antennas to obtain the characteristics of high directivity and high gain, which can be used for long-distance propagation. Once designed, the above antennas have fixed performance and are called "static antennas", but they cannot be adjusted, and there are certain limitations in the use process.

[0003] To further optimize the performance of antennas, enhance their practicability, and achieve adjustable antenna functions, people have designed and proposed "quasi-static antennas" such as phased array antennas and reconfigurable antennas, which regulate the amplitude and phase of metasurface units to adjust antenna characteristics. The core of a phased array antenna is a phase shifter, but its usage cost is relatively high. To further reduce energy consumption and optimize the design, a reconfigurable antenna array is usually composed of a large number of reconfigurable antenna units arranged periodically. By controlling the on / off of reconfigurable devices integrated on the antenna units, such as PIN diodes, the radiation state of the antenna units can be dynamically controlled, and multi-bit quantization regulation can be performed on each unit of the array to achieve an ideal transceiver effect. In the design of large-scale reconfigurable antennas, currently, independent multiple switches are used, which will lead to too high complexity, and using pin diodes as switches will result in high power consumption and is not conducive to practical applications. In addition, quasi-static antennas can adjust the unit characteristics according to the usage scenario of the antenna, but they still play a static role during the use of the antenna.

[0028] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0030] The following gives a simple explanation of the terms related to the present invention.

[0031] The following Figures 1 - 10 describes the computational antenna and control method based on spatio-temporal digital control signal regulation of the present invention.

[0032] Figure 1 is a schematic diagram of the computational antenna based on spatio-temporal digital control signal regulation provided by the present invention. As Figure 1 shown, the computational antenna includes: A computational antenna array, including at least two reconfigurable antenna elements.

[0033] A radio frequency switch chip, which may include a digital signal input port and at least two groups of radio frequency output ports. The radio frequency output ports are used to connect to the reconfigurable antenna elements. Among them, the radio frequency switch chip controls the radio frequency characteristics of the electromagnetic wave incident on the radio frequency output port and then reflected back by reading the spatio-temporal digital control signal input through the digital signal input port, so as to regulate the radiation state of the reconfigurable antenna element connected to the radio frequency output port. By using a multi-channel radio frequency switch chip, dynamic control in time can be achieved. The radio frequency switch chip controls the working state of each radio frequency path by reading the input signal waveform, so as to regulate the radiation state of the antenna element connected to each path. The radiation state of the reconfigurable antenna element may include: amplitude state, phase state. Multiple antenna elements are controlled by one chip, which can effectively reduce the system complexity.

[0034] In this embodiment, the spatio-temporal digital control signal is calculated based on the beamforming information of the computing antenna array. The calculation of the spatio-temporal digital control signal can be performed by a processor or a chip integrated with the computing antenna. The spatio-temporal digital control signal can be used to control the operating states of antenna elements at multiple different spatial positions and change according to a given time sequence. The radiation characteristics of such an antenna can be calculated, processed, and dynamically regulated, which is called a computing antenna. The computing antenna can be widely applied in the design of wireless systems in the microwave, millimeter-wave, and terahertz frequency bands. The beamforming information may include beamforming configurations, such as the physical layout and configuration of the antenna array, beamforming algorithms, and beamforming parameters, etc., which are information related to antenna beamforming.

[0035] In some alternative implementation manners, the computing antenna further includes a numerical control module. The numerical control module is used to calculate the spatio-temporal digital control signal according to the beamforming information to regulate the amplitude or phase of the reconfigurable antenna element. Integrating the numerical control module inside the antenna enables the antenna to have multiple functions such as signal transmission and reception, energy focusing, while also having functions such as sensing information, transmitting information, and dynamically and intelligently processing information. According to the actual scenario requirements, the amplitude and phase of the element are calculated and regulated.

[0036] In some alternative implementation manners, the radio frequency switch chip realizes the control synchronization of at least two reconfigurable antenna elements through a clock signal and an enable signal.

[0037] In some alternative implementation manners, the state of the antenna element is controlled by a binary value, that is, the antenna element is a 1-bit antenna element. When the computing antenna is receiving, it performs time-weighted average processing on the signals at preset moments to achieve equivalent multi-bit quantization. Due to the current common switching characteristics, a 2-bit design of the reconfigurable antenna requires multiple switches, while a 1-bit design has the problem of excessive quantization loss. There is an urgent need for a switch that can be highly integrated while reducing power consumption and quantization loss. Moreover, the errors introduced by low-bit quantization such as 1-bit and 2-bit for the element lead to the deterioration of the performance of the metasurface antenna, such as gain, side lobes of the radiation pattern, and bandwidth. At the same time, the high cost and complexity of higher-bit shift quantization units limit the wide application of the reconfigurable antenna array. There is an urgent need for a new technology that can achieve small quantization loss and low cost.

[0038] The computational antenna provided by this implementation method can perform single-bit quantization in the spatial domain using a radio frequency switch, and can also perform time-weighted averaging on signals at multiple moments, dynamically adjust to obtain the quantization freedom in the time domain, thereby equivalently implementing multi-bit quantization. This method greatly simplifies the design of the physical structure in the spatial domain, making the computational antenna have the advantages of low complexity, low power consumption, low cost, light weight, easy conformal, large bandwidth, etc., and is easy to expand towards high frequency bands and large apertures. At the same time, the computational antenna can adjust the waveform of the spatio-temporal digital control signal to achieve functions such as beam scanning, low sidelobe beam, and main lobe anti-jamming.

[0039] In some alternative implementation methods, performing time-weighted averaging on the signal at a preset moment includes: Performing time-weighted averaging on the radiation patterns of the center frequencies at

[0040] For the implementation of a reconfigurable antenna array of traditional "quasi-static antennas", generally 1-bit or multi-bit switching devices are used for phase shift design. Taking a 3-bit switching device as an example, its quantization accuracy is , that is, the antenna element can generate 8 phase differences of 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees under the switching of 8 modes. The higher the number of bits, the more accurate the quantization result and the better the antenna effect. The quantization error caused by a lower number of bits makes the antenna performance poor, while a higher number of bits leads to complex design and too high cost.

[0041] The computational antenna of this implementation method can not only perform beamforming on traditional array antenna elements to achieve 1-bit quantization in the spatial domain, but also perform time-weighted averaging on signals at multiple moments, dynamically adjust to obtain the quantization freedom of (n - 1) bits in the time domain, and introduce the freedom in time. It can use 1-bit switching hardware to achieve equivalent n-bit phase shift, greatly simplifying the design of the physical structure in the spatial domain, thereby reducing quantization loss and improving antenna performance.

[0042] The multi-channel radio frequency switch chip includes N groups of radio frequency output ports (N is an integer greater than or equal to 2). Each group of radio frequency ports is connected to an antenna element. A radio frequency switch chip can control the radiation state of the antenna element by controlling the radio frequency characteristics of electromagnetic waves to be reflected back to the radio frequency port, thereby controlling the amplitude or phase. The multi-channel radio frequency switch chip includes a digital signal input port. By changing the waveform of the spatio-temporal digital control signal of the digital signal, the radiation states of each antenna element are controlled through the on-off of the switch, and its structure is as Figure 2 shown. During the transmission of a data or information, the reconfigurable antenna array has traversed the state of a unit, and on this basis, by performing time-weighted averaging and dynamic adjustment on the signals of all states at a certain moment, the final equivalent radiation pattern can be obtained.

[0043] For example, four units are selected on the antenna array to achieve phase shifts of 0°, 45°, 90°, and 135° respectively. In the prior art, a 3-bit switch is usually selected for quantization. In this implementation, a 1-bit antenna array is used. By introducing four groups of switch states at four different times, the same effect can be achieved, as Figure 3 shown. The switch can be set to the off state, and when the phase shift is 0°, it is recorded as the low level "0". When the switch is set to the on state, and the phase shift is 180°, it is recorded as the high level "1". An antenna unit transmitting a signal experiences 8 state switches during the transmission process. By performing time-weighted averaging on the radiation patterns of the 8 states, a result similar to that of a multi-bit switch can be achieved. As Figure 3 shown, for the timing signal of unit 1, the average of four 0°s of "0000" gives a phase shift of 0°; for the timing signal of unit 2, the average of three 0°s and one 180° of "0001" gives a phase shift of 45°; for the timing signal of unit 3, the average of two 0°s and two 180°s of "0011" gives a phase shift of 90°; for the timing signal of unit 4, the average of one 0° and three 180°s of "0111" gives a phase shift of 135°.

[0044] The performance of the computational antenna is simulated and measured. The results are consistent with and in agreement with the above theoretical values, effectively realizing functions such as beam focusing and scanning, equivalent multi-bit, sidelobe reduction, and main lobe anti-interference.

[0045] By calculating and setting different switch states at different times, the computational antenna array can achieve beam focusing and scanning at different angles, and under the same incident conditions, achieve different angles of emission. The simulated radiation pattern effect is as Figure 4 shown.

[0046] By comparing the radiation pattern of the computational antenna array composed of 1-bit switches and 2-bit time degrees of freedom with the results of traditional phase shifters, 2-bit, and 3-bit switch phase shift processing, as Figure 5 shown, it is found that the effect of the computational antenna array is almost in agreement with that of a 3-bit reconfigurable antenna array.

[0047] Performing time-weighted averaging on the four different radiation patterns obtained from the four groups of switch phase shift states at four different times, as Figure 6As shown, the computational antenna array regulated by spatio-temporal digital signals effectively achieves the effect of reducing sidelobes. By performing time-weighted averaging on different radiation patterns in different time periods and different switch states, compared with the radiation pattern without averaging, the main lobe after averaging is more prominent, realizing a strong anti-interference function for the main lobe. In summary, the 1-bit switch computational antenna array and the (n - 1)-bit time degree of freedom jointly achieve the effect of equivalent n-bit quantization.

[0048] In some alternative implementation manners, complementary metal-oxide-semiconductor (CMOS) switches are adopted inside the radio frequency switch chip. The use of CMOS switches can effectively reduce the DC power consumption, and at the same time, the voltage-controlled characteristic enables the simplification of the DC bias circuit.
