Description

Technical Field

[0001] This utility model belongs to the field of microstrip rectifier technology, and more specifically, relates to a wide dynamic range microstrip rectifier. Background Technology

[0002] A microstrip rectifier is an electronic device based on microstrip circuit technology, primarily used to convert microwave or radio frequency signals into DC signals. In the field of microwave wireless power transmission systems, the microstrip rectifier is a key component, and its performance plays a decisive role in the overall system efficiency. However, traditional microstrip rectifiers face many challenges in practical applications, the main problems including:

[0003] 1) Unstable energy conversion efficiency: In non-constant RF environments, traditional microstrip rectifiers struggle to adapt to fluctuations in input power. When the input power is low, the rectification efficiency is low, making it impossible to effectively collect and convert energy; while when the input power is too high, saturation is likely to occur, leading to a sharp drop in efficiency and an inability to stably convert RF energy into DC energy, severely affecting the stability of the system's energy supply.

[0004] 2) Narrow Applicable Dynamic Range: Existing microstrip rectifiers have a narrow operating dynamic range, which cannot meet the power input requirements of various application scenarios. In some practical applications, such as IoT devices and wearable devices, the distance between the signal source and the microstrip rectifier changes constantly, resulting in a large dynamic range of input power variation. Traditional rectifiers struggle to maintain efficient operation in such environments.

[0005] 3) Material limitations restrict performance: Some traditional microstrip rectifiers use materials with insufficient high-frequency performance. For example, some commonly used substrates have high dielectric constants and loss tangents, resulting in significant energy loss when processing high-frequency signals. This makes it difficult to improve the overall performance of the microstrip rectifier and limits its application in scenarios with high high-frequency performance requirements.

[0006] These problems arise primarily from the lack of an effective management mechanism for different input power in the structural design of traditional microstrip rectifiers, and the failure to fully balance cost and performance in material selection. Attempts to solve these problems face challenges such as complex circuit design, difficulty in cost control, and the challenge of achieving breakthroughs in material performance.

[0037] The specific embodiments of this utility model will now be described with reference to the accompanying drawings to enable those skilled in the art to better understand this utility model. It should be particularly noted that in the following description, detailed descriptions of known functions and designs that might obscure the main content of this utility model will be omitted here.

[0038] Figure 1 This is a structural diagram illustrating a specific embodiment of the wide dynamic range microstrip rectifier of this utility model. (See diagram for example.) Figure 1 As shown, the wide dynamic range microstrip rectifier of this utility model includes a four-port power bridge 1, a first main rectifier 2, a second main rectifier 3, and a secondary rectifier 4, wherein:

[0039] One port 11 of the four-port energy bridge 1 is connected to the input signal, and the energy of the input signal is distributed one-to-one to the two ports 12 and 13. The two ports 12 are connected to the input terminal of the first main rectifier 2, the three ports 13 are connected to the input terminal of the second main rectifier 3, and the four ports 14 are connected to the input terminal of the secondary rectifier 4.

[0040] The first main rectifier 2, the second main rectifier 3, and the secondary rectifier 4 rectify and output their respective input signals.

[0041] As described above, in this microstrip rectifier, most of the energy enters the first main rectifier 2 and the second main rectifier 3 via the two-port 12 and the three-port 13, while a small portion of the reflected energy is transmitted to the secondary rectifier 4 via the four-port 14. This design effectively reduces the variation of input energy at the rectification point, indirectly expanding the effective operating frequency band of the microrectifier.

[0042] This invention employs three rectifiers. The first main rectifier 2 and the second main rectifier 3 have the same input signal power, while the secondary rectifier 4 has a smaller input signal power. Therefore, different rectifier topologies can be used to adapt to different input power and frequency bands. After passing through a four-port power bridge, most of the energy enters the first main rectifier 2 and the second main rectifier 3. A small portion, due to signal reflections at two ports (12) and three ports (13), enters the secondary rectifier 4. Through the coordinated operation of the two main rectifiers and the secondary rectifier, the rectification efficiency is increased.

[0043] Since the input signal power of the first main rectifier 2 and the second main rectifier 3 is the same, the same structure is adopted in this embodiment. Figure 2 This is a structural diagram of the two main rectifiers in this embodiment. (See diagram below.) Figure 2 As shown, in this embodiment, the first main rectifier 2 and the second main rectifier 3 include a first microstrip line TL1, a first DC blocker DC_BLOCK1, a second microstrip line TL2, a first microstrip line open-circuit terminal MLOC, a third microstrip line TL3, a first diode DIODE1, a fourth microstrip line TL4, a second diode DIODE2, a fifth microstrip line TL5, a sixth microstrip line TL6, a first inductor L, a seventh microstrip line TL7, a first capacitor C1, an eighth microstrip line TL8, a ninth microstrip line TL9, a tenth microstrip line TL10, and a second capacitor C2, wherein:

[0044] One end of the first microstrip line TL1 is connected to the input terminal P1, and the other end is connected to the first DC blocker DC_BLOCK1. The other end of the first DC blocker DC_BLOCK1 is connected to the second microstrip line TL2. The other end of the second microstrip line TL2 is connected to the microstrip line open terminal MLOC, the third microstrip line TL3, the positive terminal of the first diode DIODE1, and the fourth microstrip line TL4. The other end of the first diode DIODE1 is left floating.

[0045] The other end of the third microstrip line TL3 is connected to the negative terminal of the second diode DIODE2. The positive terminal of the second diode DIODE2 is connected to the fifth microstrip line TL5. The other end of the fifth microstrip line TL5 is connected to the sixth microstrip line TL6. The other end of the sixth microstrip line TL6 is connected to the grounding hole.

[0046] The other end of the fourth microstrip line TL4 is connected to the first inductor L1, the other end of the first inductor L1 is connected to the seventh microstrip line TL7, and the other end of the seventh microstrip line TL7 is connected to the negative terminal of the first capacitor C1 and the tenth microstrip line TL10, respectively.

[0047] The positive terminal of the first capacitor C1 is connected to the eighth microstrip line TL8, and the other end of the eighth microstrip line TL8 is connected to the ninth microstrip line TL9. The ninth microstrip line TL9 is connected to the grounding hole.

[0048] The other end of the tenth microstrip line TL10 is connected to the negative terminal of the second capacitor C2 and the output terminal P2, respectively, and the positive terminal of the second capacitor C2 is grounded.

[0049] Since the power of the secondary rectifier 4 is smaller than that of the first main rectifier 2 and the second main rectifier 3, the structure of the secondary rectifier 4 in this embodiment is different from that of the first main rectifier 2 and the second main rectifier 3. Figure 3 This is a structural diagram of the secondary rectifier in this embodiment. (See diagram below.) Figure 3 As shown, in this embodiment, the secondary rectifier includes a twelfth microstrip line TL12, a thirteenth microstrip line TL13, a second DC-Block 2, a fourteenth microstrip line TL14, a fifteenth microstrip line TL15, a third diode DIODE3, a sixteenth microstrip line TL16, a second inductor L2, a seventeenth microstrip line TL17, a third inductor L3, an eighteenth microstrip line TL18, a nineteenth microstrip line TL19, a third DC-Block 3, a twentieth microstrip line TL20, a fourth DC-Block 4, and a twenty-first microstrip line TL21, wherein:

[0050] One end of the twelfth microstrip line TL12 is connected to the input terminal P1, and the other end is connected to the thirteenth microstrip line TL13. The other end of the thirteenth microstrip line TL13 is connected to the second DC blocker DC_BLOCK2. The other end of the second DC blocker DC_BLOCK2 is connected to the fourteenth microstrip line TL14. The other end of the fourteenth microstrip line TL14 is connected to the fifteenth microstrip line TL15 and the negative terminal of the third diode DIODE3, respectively.

[0051] The positive terminal of the third diode DIODE3 is connected to the sixteenth microstrip line TL16. The other end of the sixteenth microstrip line TL16 is connected to the second inductor L2. The other end of the second inductor L2 is connected to the seventeenth microstrip line TL17. The other end of the seventeenth microstrip line TL17 is connected to the ground hole.

[0052] The other end of the fifteenth microstrip line TL15 is connected to the third inductor L3, the other end of the third inductor L3 is connected to the eighteenth microstrip line TL18, and the other end of the eighteenth microstrip line TL18 is connected to the nineteenth microstrip line TL19 and the third DC blocker DC_BLOCK3, respectively.

[0053] The other end of the third DC blocker DC_BLOCK3 is connected to the twentieth microstrip line TL20, and the other end of the twentieth microstrip line TL20 is connected to the grounding hole.

[0054] The other end of the nineteenth microstrip line TL19 is connected to the output terminal P2 and the fourth DC blocker DC_BLOCK4, respectively. The other end of the fourth DC blocker DC_BLOCK4 is connected to the twenty-first microstrip line TL21, and the other end of the twenty-first microstrip line TL21 is grounded.

[0055] As described above, in this embodiment, the matching network is optimized according to the different operating frequencies and input power of the main rectifier and the secondary rectifier, thereby achieving good matching between the rectifier and the input signal source, reducing reflection loss, and improving energy transmission efficiency.

[0056] In practical applications, the three output signals can be combined as needed. When merging is required, a combiner can be added to the microstrip rectifier of this utility model to combine the outputs of the first main rectifier 2, the second main rectifier 3 and the secondary rectifier 4 into one signal for output.

[0057] In this embodiment, the substrate for the wide dynamic range microstrip rectifier can be either FR4 or F4B-2 (polytetrafluoroethylene) substrate. FR4 substrate has a lower cost and is suitable for cost-sensitive large-scale applications. Testing has shown that rectifiers based on FR4 substrate can achieve a S11 of -15dB. F4B-2 substrate has advantages such as low processability thickness, low dielectric constant, and low loss tangent, making it suitable for high-performance applications. In simulations, rectifiers based on this substrate can achieve a S11 of -30dB at 2.3GHz.

[0058] To better illustrate the technical effects of this utility model, specific examples are used to simulate and verify it. Figure 4 This is a structural diagram of the wide dynamic range microstrip rectifier of this invention in this embodiment. Figure 4 As shown, in this embodiment, one port PORT1 of the four-port power bridge is connected to the input signal (a wave with a frequency of 2.45 GHz and an energy level between 0 dBm and 30 dBm).
