Description

Technical Field

[0001] This invention belongs to the field of electronic connector technology, and particularly relates to an electronic connector with antenna function and its anti-interference method. Background Technology

[0002] Currently, the Internet of Things, smart wearable devices, and mobile communication devices are iterating towards extreme miniaturization. The internal space of printed circuit boards (PCBs) is being highly compressed, and every inch of space needs to be used efficiently. The antenna configuration, which is essential for wireless communication functions, is facing a space dilemma. The electronic connectors used in 2.4GHz wireless keyboards and mice are generally compatible with USB 2.0 interfaces, while most mainstream host computers are equipped with USB 3.0 / 3.1 / USB-C ports. When such connectors are connected, they will be directly exposed to the broadband noise generated by high-speed USB 3.x differential pairs.

[0003] The operation of USB 3.x interfaces significantly raises the noise floor in the 2.4-2.5GHz frequency band, severely interfering with the stability of wireless communication. The choice of antenna topology is crucial. Although existing PIFA antennas and chip antennas perform well in systems with controlled ground planes and sufficient chassis space, in electronic connector scenarios, they are limited by finite and discontinuous ground planes, structural differences between hosts, and the strong coupling effect of near-field USB noise, resulting in extremely poor adaptability and significant fluctuations in communication performance. Monopole antennas can reduce noise coupling and have better adaptability because they do not require short-circuit pins between the radiator and the PCB ground. However, existing connectors still have obvious defects. Improper force during insertion and removal can easily cause physical damage to the interface and connector. When idle, the connector is exposed, and dust can easily enter the interior, leading to poor contact, short circuits, and other faults, greatly shortening the product life and making it difficult to meet the market's demand for reliability. In view of this, we propose an electronic connector with antenna function and its anti-interference method. Summary of the Invention

[0004] The purpose of this invention is to provide an electronic connector with an antenna function and its anti-interference method to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an electronic connector with antenna function and an anti-interference method thereof, comprising:

[0006] The metal casing contains an insulating body fixedly installed inside. A connecting plug is provided on one side of the insulating body, and a conductive terminal group is provided on the connecting plug. A PCB board is provided on the other side of the insulating body, and a radiating antenna is provided on the PCB board. A buffer plate is provided around the connecting plug, and a buffer pad is fixedly installed on one side of the buffer plate.

[0007] A buffer assembly, located within a metal housing, is used to cushion the buffer plate;

[0008] A fixing component, located within a metal housing, is used to fix the buffer plate;

[0009] A protective cover is rotatably mounted on one side of a metal casing. A sealing ring is fixedly mounted on one side of the protective cover, and a locking block is fixedly mounted on one side of the protective cover. One end of the locking block extends into the metal casing.

[0010] A reset assembly, located within a metal housing, is used to reset the protective cover.

[0011] In this technical solution, during use, the user can insert the connector into the receiving end of the computer. During the insertion process, the buffer plate will be squeezed and moved. At the same time, the buffer pad on the buffer plate can provide an initial buffering effect. Subsequently, the movement of the buffer plate will squeeze the buffer component for further buffering. The buffer component can provide a second buffering for the connector, preventing the connector from being damaged due to the user's forceful insertion.

[0012] Meanwhile, the buffer plate is fixed by the fixing component until the connecting plug is fully inserted into the computer's connection port. When pulling out, simply release the fixing component. At this time, under the action of the rebound force of the buffer component, the buffer component will drive the buffer plate to reset, thereby squeezing the computer interface until the entire device pops out, ensuring that it can be easily pulled out by personnel without effort and without damaging the connecting plug.

[0013] When not in use, the clips on the protective cover can be fastened onto the metal casing to seal it. The sealing ring prevents dust from entering the connector and avoids damage caused by dust entering the connector.

[0014] In the above technical solution, the buffer component further includes:

[0015] Two buffer slots are provided, both of which are located inside a metal casing. A buffer rod is slidably installed in each buffer slot. One end of the buffer rod passes through one side of the buffer slot and is fixedly connected to a buffer plate. A guide rod is fixedly installed on the other side of the buffer slot, and a buffer spring is sleeved on the guide rod.

[0016] In this technical solution, personnel can insert the connector into the receiving end of the computer. During the insertion process, the buffer plate will be squeezed and moved. At the same time, the buffer pad on the buffer plate can provide an initial buffering effect. Subsequently, the movement of the buffer plate will drive the two buffer rods to move. The movement of the buffer rods will compress the buffer spring and contract it. Under the buffering effect of the buffer spring, the connector can be buffered a second time, avoiding damage to the connector caused by personnel forcefully inserting it.

[0017] In the above technical solution, furthermore, the two ends of the buffer spring are tightly welded to the buffer rod and the inner wall of the buffer groove, respectively, and one end of the buffer rod is tightly welded to the buffer plate.

[0018] In this technical solution, the structural stability of the buffer spring is ensured, as are the structural stability of the buffer rod and the buffer plate.

[0019] In the above technical solution, the fixing component further includes:

[0020] Two movable slots are symmetrically opened inside the metal shell. Two limiting steel balls are provided in each movable slot. A movable plate is slidably installed in each movable slot. Two pressing plates are fixedly installed on one side of the movable plate. One end of the pressing plate abuts against the corresponding limiting steel ball. One side of the movable plate extends through the movable slot to the outside and is fixedly installed with a pressing plate. Several round rods are fixedly installed on one side of the movable slot. A spring is sleeved on each round rod.

[0021] In this technical solution, pressing two pressing plates causes the moving plate to move, which in turn moves two pressing plates until one end of the pressing plate moves out from one side of the limiting steel ball, thus releasing the limiting steel ball. Once the connecting plug is fully inserted into the computer's connector, the two pressing plates are released. Under the rebound force of several springs, the springs press the moving plate to reset, which in turn moves the two pressing plates to reset. The pressing plates then press the limiting steel ball to reset, until one end of the limiting steel ball is inserted into the buffer plate, thus fixing the buffer plate. When removing the device, simply release the four limiting steel balls. Under the rebound force of the two buffer springs, the buffer springs press the buffer rod to reset, which in turn moves the buffer plate to reset, thus pressing the computer interface until the entire device pops out. This ensures easy removal without effort and without damaging the connecting plug.

[0022] In the above technical solution, the limiting steel ball is further engaged with the buffer plate, the extrusion plate is slidably connected to the movable groove, and the two ends of the spring are respectively tightly welded to the moving plate and the inner wall of the movable groove.

[0023] In this technical solution, the limiting steel ball is ensured to limit the buffer plate, and the extrusion plate is guaranteed to slide normally in the movable groove, ensuring the structural stability of the spring.

[0024] In the above technical solution, the reset component further includes:

[0025] Two rotating slots are symmetrically opened inside the metal shell. A rotating rod is rotatably installed in each rotating slot. One end of the rotating rod passes through one side of the rotating slot and is coaxially connected to the rotating shaft of the protective cover. A torsion spring is sleeved on the rotating rod and located inside the rotating slot.

[0026] In this technical solution, when the protective cover is opened, the torsion force of the two torsion springs will cause the rotating rod to rotate, and the rotation of the rotating rod will cause the protective cover to rotate, thereby automatically opening the protective cover and avoiding obstruction of the insertion by the protective cover.

[0027] In the above technical solution, furthermore, the two ends of the torsion spring are tightly welded to the rotating rod and the inner wall of the rotating groove, respectively, and the rotating rod is rotatably connected to the metal shell.

[0028] In this technical solution, the structure of the torsion spring is ensured to be stable, guaranteeing that the rotating rod can rotate normally within the metal casing.

[0029] In the above technical solution, the card block is further engaged with the metal shell, and the sealing ring is in close contact with one side of the metal shell.

[0030] In this technical solution, it is ensured that the card block can be locked onto the metal shell, and that the sealing ring can seal the metal shell.

[0031] The above technical solution further includes the following methods:

[0032] S1. The antenna radiating part and the grounding part of the connector are electrically isolated at the radio frequency signal feed point, or designed into an inverted F-type antenna (PIFA) architecture through a specific short-circuit pin.

[0033] S2. Assuming it is for the 2.4GHz band, the electrical length of the antenna radiating part is designed to be about 30mm, and the electrical length of the quarter wavelength is designed to be about 3.125mm; for the 5GHz band, the length is about 15mm, and the electrical length of the quarter wavelength is about 1.5mm. By using the metal structure and three-dimensional height that the connector itself must have to make the antenna, the planar space on the PCB board is freed up, which is conducive to the miniaturization design of the product.

[0034] S3 eliminates the procurement cost of additional chip antennas or flexible board antennas, while reducing assembly steps. The connector is usually fixed by soldering reinforced DIP or SMT pins. Using this solid foundation as the antenna carrier, it is more resistant to vibration and impact than simple suspended wires. The antenna is located directly on the connector at the edge of the PCB, which shortens the transmission path of RF signals on the PCB and reduces transmission loss.

[0035] S4. Due to the extremely limited internal space of electronic connectors, monopole antennas cannot be physically separated from the metal housing of electronic connectors (such as USB). However, even in such a constrained environment, the sensitivity of monopoles to ground noise of USB 3.x is reduced because they do not include low-impedance short-circuit pins connected to PCB ground, their ground reference is primarily capacitive rather than conductive, and conducted noise from the housing of electronic connectors (such as USB) has no direct path to the heat sink. This structural feature—rather than physical distance—reduces the degree of interaction between EMI generated by monopoles and USB.

[0036] S5. Different laptops / desktops vary significantly in the following aspects: USB 3.x routing, shielding, grounding impedance, and chassis mode. Under these different host conditions, our measurements show that the monopole implementation exhibits less drift in S11, efficiency, and radiation pattern compared to PIFA or chip antennas. This is primarily because the monopole does not force the main ground current into its resonant path. Although all antennas are affected by the near-field E / H field of the electronic connector (such as USB), the monopole has no short-circuit pins. This prevents the grounding noise of the electronic connector (such as USB) housing from directly interfering with the resonant current distribution. This results in reduced near-field conducted coupling, reduced ground noise injection, and lower resonant disturbances despite being very close to the electronic connector (such as USB) housing. These effects collectively contribute to the higher stability of the compact electronic connector platform in the real world.

[0037] The beneficial effects of this invention are:

[0038] 1. This electronic connector with antenna function and its anti-interference method adopt a monopole antenna topology. With the design of no radiator and PCB ground short-circuit pin, it significantly reduces the coupling of USB3.x ground noise to the antenna resonant structure, effectively avoids noise interference in the 2.4-2.5GHz band, significantly improves the stability and consistency of 2.4GHz band wireless communication on different USB3.x hosts, and adapts to complex host environments.

[0039] 2. This electronic connector with antenna function and its anti-interference method include an added insertion and removal buffer structure. The elastic buffer design offsets excessive force during insertion and removal, preventing physical damage to the interface and connector caused by impact and compression, reducing maintenance costs, and extending the connector's service life. It is equipped with a connector sealing structure, which can quickly seal the connector when idle, completely preventing dust and impurities from entering, preventing oxidation of internal metal contacts and poor contact, and ensuring long-term reliability. Fourthly, the overall structure is adapted to the miniaturization requirements of equipment, achieving dual functions of anti-interference and physical protection within a limited PCB space without occupying additional space. It balances performance and practicality, enhances the product's market competitiveness, and meets the core requirements of IoT devices for efficient and durable connectors.

[0056] Example 1:

[0057] Please see Figure 1 - Figure 9 As shown, this embodiment provides an electronic connector with antenna functionality, including:

[0058] Metal casing 1, insulating body 2 is fixedly installed inside the metal casing 1, connecting plug 3 is provided on one side of the insulating body 2, conductive terminal group 4 is provided on the connecting plug 3, PCB board 5 is provided on the other side of the insulating body 2, radiating antenna 6 is provided on the PCB board 5, buffer plate 7 is provided around the connecting plug 3, buffer pad 8 is fixedly installed on one side of the buffer plate 7.

[0059] A buffer assembly, located inside the metal housing 1, is used to buffer the buffer plate 7;

[0060] A fixing component is located inside the metal housing 1 and is used to fix the buffer plate 7.

[0061] The protective cover 19 is rotatably mounted on one side of the metal shell 1. A sealing ring 20 is fixedly installed on one side of the protective cover 19. A locking block 21 is fixedly installed on one side of the protective cover 19. One end of the locking block 21 extends into the metal shell 1.

[0062] A reset assembly is located inside the metal housing 1 and is used to reset the protective cover 19.

[0063] In use, the user can insert the connector 3 into the receiving end of the computer. During the insertion process, the buffer plate 7 will be squeezed and moved. At the same time, the buffer pad 8 on the buffer plate 7 can provide an initial buffering effect. Subsequently, the movement of the buffer plate 7 will squeeze the buffer component for buffering. The buffer component can provide a second buffering for the connector 3, preventing the connector 3 from being damaged due to the user's forceful insertion.

[0064] Meanwhile, when the connecting plug 3 is fully inserted into the computer's connection port, the buffer plate 7 is fixed by the fixing component. When pulling out, simply release the fixing component from its limit. At this time, under the action of the rebound force of the buffer component, the buffer component will drive the buffer plate 7 to reset, thereby squeezing the computer interface until the entire device pops out, ensuring that it can be easily pulled out by personnel without effort and without damaging the connecting plug 3.

[0065] When not in use, the clip 21 on the protective cover 19 can be clipped onto the metal casing 1 to seal the metal casing 1. Under the sealing effect of the sealing ring 20, dust can be prevented from entering the connecting plug 3, thus avoiding damage caused by dust entering the connecting plug 3.

[0066] Example 2:

[0067] This embodiment provides an electronic connector with an antenna function. In addition to the technical solutions of the above embodiments, it also has the following technical features: the buffer component includes:

[0068] Two buffer grooves 9 are provided, both of which are located inside the metal casing 1. A buffer rod 10 is slidably installed inside the buffer groove 9. One end of the buffer rod 10 passes through one side of the buffer groove 9 and is fixedly connected to the buffer plate 7. A guide rod 11 is fixedly installed on the other side of the buffer groove 9, and a buffer spring 12 is sleeved on the guide rod 11.

[0069] The user can insert the connector 3 into the computer's receiving end. During the insertion process, the buffer plate 7 will be squeezed and moved. At the same time, the buffer pad 8 on the buffer plate 7 can provide an initial buffering effect. Subsequently, the movement of the buffer plate 7 will drive the two buffer rods 10 to move. The movement of the buffer rods 10 will compress the buffer spring 12 and cause it to contract. Under the buffering effect of the buffer spring 12, the connector 3 can be buffered a second time, preventing the connector 3 from being damaged due to the user's forceful insertion.

[0070] Example 3:

[0071] This embodiment provides an electronic connector with an antenna function. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two ends of the buffer spring 12 are tightly welded to the inner wall of the buffer rod 10 and the buffer groove 9, respectively, and one end of the buffer rod 10 is tightly welded to the buffer plate 7.

[0072] This ensures the structural stability of the buffer spring 12 and guarantees the structural stability of the buffer rod 10 and the buffer plate 7.

[0073] Example 4:

[0074] This embodiment provides an electronic connector with antenna functionality. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a fixing component:

[0075] Two movable slots 13 are symmetrically opened inside the metal shell 1. Two limiting steel balls 14 are provided in the movable slots 13. A movable plate 16 is slidably installed in the movable slots 13. Two pressing plates 15 are fixedly installed on one side of the movable plate 16. One end of the pressing plate 15 abuts against the corresponding limiting steel ball 14. One side of the movable plate 16 extends through the movable slots 13 to the outside and is fixedly installed with a pressing plate 25. Several round rods 17 are fixedly installed on one side of the movable slots 13. Springs 18 are sleeved on the round rods 17.

[0076] When the two pressing plates 25 are pressed, the movement of the pressing plates 25 causes the moving plate 16 to move, which in turn causes the two pressing plates 15 to move until one end of the pressing plate 15 moves out of the limiting steel ball 14, thus releasing the limiting steel ball 14. When the connecting plug 3 is fully inserted into the computer's connector, the pressing plates 25 are released. Under the rebound force of several springs 18, the springs 18 will press the moving plate 16 to reset, and the moving plate 16 will then cause the two pressing plates 15 to reset. When the pressure plate 15 is in position, it will press the limiting steel ball 14 to reset until one end of the limiting steel ball 14 is inserted into the buffer plate 7, thereby fixing the buffer plate 7. When pulling out, it is only necessary to release the four limiting steel balls 14. At this time, under the action of the rebound force of the two buffer springs 12, the buffer spring 12 will press the buffer rod 10 to reset. The buffer rod 10 will drive the buffer plate 7 to reset, thereby pressing the computer interface until the entire device pops out, ensuring that it can be easily pulled out by personnel without effort and without damaging the connecting plug 3.

[0082] Two rotating slots 22 are symmetrically opened inside the metal shell 1. A rotating rod 23 is rotatably installed inside the rotating slot 22. One end of the rotating rod 23 passes through one side of the rotating slot 22 and is coaxially connected to the rotating shaft of the protective cover 19. A torsion spring 24 is sleeved on the rotating rod 23 and located inside the rotating slot 22.

[0083] When the protective cover 19 is opened, under the torsional force of the two torsion springs 24, the torsion springs 24 will drive the rotating rod 23 to rotate. The rotation of the rotating rod 23 will drive the protective cover 19 to rotate, thereby automatically opening the protective cover 19 and preventing the protective cover 19 from obstructing the insertion.

[0084] Example 7:

[0085] This embodiment provides an electronic connector with an antenna function. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two ends of the torsion spring 24 are tightly welded to the inner wall of the rotating rod 23 and the rotating groove 22, respectively, and the rotating rod 23 is rotatably connected to the metal shell 1.

[0086] This ensures the structural stability of the torsion spring 24 and guarantees that the rotating rod 23 can rotate normally within the metal casing 1.

[0087] Example 8:

[0088] This embodiment provides an electronic connector with an antenna function. In addition to the technical solutions of the above embodiments, it also has the following technical features: the locking block 21 is engaged with the metal shell 1, and the sealing ring 20 is in close contact with one side of the metal shell 1.

[0089] Specifically, this ensures that the locking block 21 can be locked onto the metal casing 1, and that the sealing ring 20 can seal the metal casing 1.

[0090] Example 9:

[0091] This embodiment provides an anti-interference method, which, in addition to the technical solutions of the above embodiments, also has the following technical features and includes the following methods:

[0092] S1. The antenna radiating part and the grounding part of the connector are electrically isolated at the RF signal feed point. If it is a monopole antenna architecture, it can be designed as an inverted F-type antenna (PIFA) architecture through a specific short-circuit pin.

[0093] S2. Assuming it is for the 2.4GHz band, the electrical length of the antenna radiating part is designed to be about 30mm, adjusted according to the dielectric constant, and the electrical length of the 1 / 4 wavelength is designed to be about 3.125mm; for the 5GHz band, the length is about 15mm, and the electrical length of the 1 / 4 wavelength is about 1.5mm; by using the metal structure and three-dimensional height that the connector itself must have to make the antenna, the planar space on the PCB board is freed up, which is conducive to the miniaturization design of the product.

[0094] S3 eliminates the procurement cost of additional chip antennas or flexible board antennas, while reducing assembly steps. The connector is usually fixed by soldering reinforced DIP or SMT pins. Using this solid foundation as the antenna carrier, it is more resistant to vibration and impact than simple suspended wires. The antenna is located directly on the connector at the edge of the PCB, which shortens the transmission path of RF signals on the PCB and reduces transmission loss.

[0095] S4. Due to the extremely limited internal space of electronic connectors, monopole antennas cannot be physically separated from the metal housing of electronic connectors (such as USB). However, even in such a constrained environment, the sensitivity of monopoles to ground noise of USB 3.x is reduced because they do not include low-impedance short-circuit pins connected to PCB ground, their ground reference is primarily capacitive rather than conductive, and conducted noise from the housing of electronic connectors (such as USB) has no direct path to the heat sink. This structural feature—rather than physical distance—reduces the degree of interaction between EMI generated by monopoles and USB.

[0096] S5. Different laptops / desktops vary significantly in the following aspects: USB 3.x routing, shielding, grounding impedance, and chassis mode. Under these different host conditions, our measurements show that the monopole implementation exhibits less drift in S11, efficiency, and radiation pattern compared to PIFA or chip antennas. This is primarily because the monopole does not force the main ground current into its resonant path. Although all antennas are affected by the near-field E / H field of the electronic connector (such as USB), the monopole has no short-circuit pins. This prevents the grounding noise of the electronic connector (such as USB) housing from directly interfering with the resonant current distribution. This results in reduced near-field conducted coupling, reduced ground noise injection, and lower resonant disturbances despite being very close to the electronic connector (such as USB) housing. These effects collectively contribute to the higher stability of the compact electronic connector platform in the real world.

[0097] It is worth noting that the radiating antenna 1-6 can also be replaced with the radiating antenna 2-26. Both the radiating antenna 1-6 and the radiating antenna 2-26 can effectively avoid noise interference in the 2.4-2.5GHz band, significantly improve the stability and consistency of 2.4GHz band wireless communication on different USB 3.x hosts, and adapt to complex host environments.

[0098] Working principle: When in use, the user can insert the connector 3 into the receiving end of the computer. During the insertion process, the buffer plate 7 will be squeezed and moved. At the same time, the buffer pad 8 on the buffer plate 7 can provide an initial buffering effect. Subsequently, the movement of the buffer plate 7 will drive the two buffer rods 10 to move. The movement of the buffer rods 10 will compress the buffer spring 12 and cause it to contract. Under the buffering effect of the buffer spring 12, the connector 3 can be buffered a second time, preventing the connector 3 from being damaged due to the user's forceful insertion.

[0099] Simultaneously, pressing the two pressing plates 25 causes the moving plate 16 to move, which in turn moves the two pressing plates 15 until one end of the pressing plate 15 moves out from one side of the limiting steel ball 14, thus releasing the limiting steel ball 14. When the connecting plug 3 is fully inserted into the computer's connector, the two pressing plates 25 are released. Under the rebound force of several springs 18, the springs 18 will press the moving plate 16 to reset, and the moving plate 16 will then move the two pressing plates 15 back to their original position. When the pressure plate 15 is in position, it will press the limiting steel ball 14 to reset until one end of the limiting steel ball 14 is inserted into the buffer plate 7, thereby fixing the buffer plate 7. When pulling out, it is only necessary to release the four limiting steel balls 14. At this time, under the action of the rebound force of the two buffer springs 12, the buffer spring 12 will press the buffer rod 10 to reset, and the buffer rod 10 will drive the buffer plate 7 to reset, thereby pressing the computer interface until the entire device pops out, ensuring that it can be easily pulled out by personnel without effort and without damaging the connecting plug 3.

[0100] When not in use, the clip 21 on the protective cover 19 can be clipped onto the metal casing 1 to seal the metal casing 1. Under the sealing effect of the sealing ring 20, dust can be prevented from entering the connecting plug 3, thus avoiding damage caused by dust entering the connecting plug 3.

9. An anti-interference method for an electronic connector with antenna function as described in any one of claims 1-8, characterized in that, Including the following methods: S1. The antenna radiating part and the grounding part of the connector are electrically isolated at the RF signal feed point (if it is a monopole antenna architecture), or designed as an inverted F-type antenna (PIFA) architecture through a specific short-circuit pin. S2. Assuming it is for the 2.4GHz band, the electrical length of the antenna radiating part is designed to be about 30mm (adjusted according to the dielectric constant), and the electrical length of the 1 / 4 wavelength is designed to be about 3.125mm; for the 5GHz band, the length is about 15mm, and the electrical length of the 1 / 4 wavelength is about 1.5mm; by using the metal structure and three-dimensional height that the connector itself must have to make the antenna, the planar space on the PCB board is freed up, which is conducive to the miniaturization design of the product. S3 eliminates the procurement cost of additional chip antennas or flexible board antennas, while reducing assembly steps. The connector is usually fixed by soldering reinforced DIP or SMT pins. Using this solid foundation as the antenna carrier, it is more resistant to vibration and impact than simple suspended wires. The antenna is located directly on the connector at the edge of the PCB, which shortens the transmission path of RF signals on the PCB and reduces transmission loss. S4. Due to the extremely limited internal space of electronic connectors, monopole antennas cannot be physically separated from the metal housing of electronic connectors (such as USB). However, even in such a constrained environment, the sensitivity of monopoles to ground noise of USB 3.x is reduced because they do not include low-impedance short-circuit pins connected to PCB ground, their ground reference is primarily capacitive rather than conductive, and conducted noise from the housing of electronic connectors (such as USB) has no direct path to the heat sink. This structural feature—rather than physical distance—reduces the degree of interaction between EMI generated by monopoles and USB. S5. Different laptops / desktops vary significantly in the following aspects: USB 3.x routing, shielding, grounding impedance, and chassis mode. Under these different host conditions, our measurements show that the monopole implementation exhibits less drift in S11, efficiency, and radiation pattern compared to PIFA or chip antennas. This is primarily because the monopole does not force the main ground current into its resonant path. Although all antennas are affected by the near-field E / H field of the electronic connector (such as USB), the monopole has no short-circuit pins. This prevents the grounding noise of the electronic connector (such as USB) housing from directly interfering with the resonant current distribution. This results in reduced near-field conducted coupling, reduced ground noise injection, and lower resonant disturbances despite being very close to the electronic connector (such as USB) housing. These effects collectively contribute to the higher stability of the compact electronic connector platform in the real world.
