Description

Technical Field

[0001] The utility model relates to the technical field of smart card structures, in particular to an antenna-optimized INLAY structure. Background Art

[0002] With the rapid development of wireless communication technology, antennas, as an important part of wireless communication systems, have a direct impact on communication quality due to their performance. In the prior art, inlay structures are a common antenna design method and are widely used in various communication devices. However, traditional inlay structure antennas often have some problems in design, such as poor signal quality and stability. These problems limit the further improvement of antenna performance and make it difficult to meet the high requirements of modern wireless communication systems for antenna performance. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art solutions, the utility model provides an antenna-optimized INLAY structure, which can effectively solve the problems raised by the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an antenna optimized INLAY structure, including a winding part and a component installation part, a chip is installed in the component installation part, the winding part is provided with a first coil and a second coil with different wire diameters, the coil is wound in the gap of the first coil by a dense winding method, and the two ends of the first coil and the second coil are respectively electrically connected to the transceiver end of the chip.

[0005] Preferably, a wire diameter of the first coil is greater than a wire diameter of the second coil.

[0006] Preferably, when the number of turns of the first coil is k, and the value of k is greater than or equal to 4, the number of turns of the second coil is less than or equal to (k-2) / 2.

[0007] Preferably, the first coil and the second coil are wound in the same direction.

[0008] Preferably, the width of the first coil is wider than the width of the second coil.

[0009] Preferably, the thickness of the winding portion is greater than the thickness of the component mounting portion.

[0010] Preferably, the gap between the winding portion and the component mounting portion is filled with a PVC base layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects: in this INLAY structure, the design of the first coil and the second coil with different wire diameters allows for more precise adjustment of the antenna impedance. By changing the wire diameter of the coil, the antenna parameters such as inductance, capacitance and resistance can be affected, thereby changing its impedance characteristics. By electrically connecting the two ends of the two coils to the transceiver end of the chip respectively, the antenna impedance can be further adjusted to match the impedance of the source or load, thereby achieving maximum power transmission and optimal signal quality.

[0012] By designing the first coil and the second coil with different wire diameters and winding them together using the close winding method, the inductance and resistance of the antenna can be adjusted to optimize its performance within a specific frequency range. The close winding method allows the second coil to be tightly wound in the gap of the first coil, increasing the coupling effect between the coils and helping to improve the frequency response characteristics of the antenna.

[0013] By adjusting the number of turns, wire diameter and winding method of the coil, the antenna's inductance, capacitance and resistance can be further controlled to achieve fine-tuning of the frequency response. This adjustment can be made according to specific application scenarios and requirements, so that the antenna has better performance in a specific frequency band. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0020] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure. Example

[0021] like Figure 1-3 As shown, the utility model provides an antenna optimized INLAY structure, including a winding part 1 and a component mounting part 2, a chip 6 is mounted in the component mounting part 2, the winding part 1 is provided with a first coil 3 and a second coil 4 with different wire diameters, the second coil 4 is wound in the gap of the first coil 3 by a close winding method, and both ends of the first coil 3 and the second coil 4 are electrically connected to the transmitting and receiving ends of the chip 6 respectively.

[0022] By designing the first coil 3 and the second coil 4 with different wire diameters and electrically connecting them to the transceiver end of the chip 6, the impedance matching and frequency response of the antenna can be optimized. This design helps to improve the transceiver performance of the antenna and enhance the transmission quality and efficiency of the signal.

[0023] By using a close winding method to wind the second coil 4 in the gap of the first coil 3, the space occupied by the antenna can be effectively reduced. This is particularly important for wireless communication devices that need to be integrated into a limited space, and helps to achieve miniaturization and lightness of the device.

[0024] The wire diameter of the first coil 3 is greater than the wire diameter of the second coil 4 .

[0025] Different wire diameters will result in different inductance and resistance values ​​of the coil. A coil with a larger wire diameter has a higher inductance value and a lower resistance value. By designing the wire diameter of the first coil 3 to be larger than that of the second coil 4, the inductance and resistance characteristics of the antenna can be optimized to meet the performance requirements under specific frequency bands and impedance conditions.

[0026] When the number of turns of the first coil 3 is k, and the value of k is greater than or equal to 4, the number of turns of the second coil 4 is less than or equal to (k-2) / 2.

[0027] When the number of turns of the first coil 3 is k (the value of k is greater than or equal to 4), the number of turns of the second coil 4 is limited to be less than or equal to (k-2) / 2. Optimizing the number of turns of the coil helps to balance the inductance and resistance of the antenna, thereby further improving the performance of the antenna.

[0028] The first coil 3 and the second coil 4 are wound in the same direction, and the width of the first coil 3 is wider than the width of the second coil 4 .

[0029] Winding the first coil 3 and the second coil 4 in the same direction and keeping the width of the first coil 3 wider than the second coil 4 can simplify the manufacturing process of the antenna and help improve the stability and reliability of the antenna.

[0030] The thickness of the winding portion 1 is greater than the thickness of the component mounting portion 2 .

[0031] By designing the thickness of the winding portion 1 to be greater than the thickness of the component mounting portion 2, the strength and stability of the antenna structure can be enhanced, which helps to resist the influence of the external environment on the antenna performance and prolong the service life of the antenna.

[0032] The gap between the winding portion 1 and the component mounting portion 2 is filled with the PVC base layer 5 .

[0033] The gap between the winding part 1 and the component mounting part 2 is filled with the PVC base layer 5, which not only plays the role of insulation and heat insulation, but also protects the internal chip 6 and other components from damage by the external environment.

[0034] In traditional antenna design, it is often necessary to make a trade-off between performance and space. Miniaturized antennas are often accompanied by reduced performance. However, this optimized INLAY structure, through clever design, not only achieves miniaturization of the antenna, but also ensures the stability of its performance.

[0035] The manufacturing process of traditional multi-coil antennas is complicated and costly. However, this structure simplifies the manufacturing process and reduces the manufacturing cost by adopting the close winding method and the same direction winding, making this antenna more competitive in the market.

[0036] The performance of the antenna under different frequency bands and impedance conditions is a key issue. By designing coils with different wire diameters and electrically connecting them to the transceiver, the antenna impedance matching and frequency response can be finely adjusted to meet the needs of different application scenarios.

"Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
