[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a wireless card reader antenna.

[0019] The above-described solutions address the problems of low card reading efficiency, slow recognition speed, and limited application range of existing card-reading antennas.

[0020] The solution is as follows: A wireless card reader antenna includes: a dielectric double-sided panel carrier 1, wherein a front radiating unit 2 is disposed on the front surface of the dielectric double-sided panel carrier 1 and a reverse radiating unit 8 is disposed on the back surface. One end of the reverse radiating unit 8 is connected to one end of the front radiating unit 2, and the other end of the front radiating unit 2 is provided with a ground-feed copper drain area 4. A power-feed copper drain area 3 is disposed on the side of the ground-feed copper drain area 4. Coaxial cables 5 are connected to the surface feed points of both the ground-feed copper drain area 4 and the power-feed copper drain area 3. An IPEX connector 6 is disposed on the side of the coaxial cable 5. Both the front and back surfaces of the dielectric double-sided panel carrier 1 are provided with covering ink 7, and the ground-feed copper drain area 4 and the power-feed copper drain area are... Domain 3 exposes the surface covered with ink 7. The dielectric double-sided carrier 1 adopts a double-sided FPC with copper foil on its surface and anti-interference black ink on both sides to protect the circuit from external damage. The front ink side is provided with a power supply copper leakage area 3 and a ground copper leakage area 4 for soldering coaxial cables 5. The coaxial cables 5 are soldered to the power supply and ground copper leakage areas. The other end of the coaxial cables 5 is installed with an IPEX connector 6 for quick connection to the device. By selecting the material and thickness of the dielectric substrate, ferrite is eliminated, reducing the antenna area and lowering enterprise costs. The array is composed of positive and negative double-sided radiating units, and the frequency coverage reaches the lower NFC frequency band, making it more suitable for current NFC card reading devices.

[0021] Further improvements, such as Figure 1 As shown: The front radiating unit 2 has a rectangular loop-shaped trace. This trace design helps to enhance the radiation efficiency and signal strength of the antenna, making the wireless card reader antenna more sensitive and stable when reading smart cards, and improving card reading efficiency.

[0022] Further improvements, such as Figure 2 As shown: The reverse radiating unit 8 is arranged in an L-shape. The L-shaped reverse radiating unit 8 can effectively expand the coverage of the antenna, so that the wireless card reader antenna can better adapt to the card reading needs in different directions, and improve the recognition speed and card reading success rate.

[0023] Further improvements, such as Figure 1 As shown: The dielectric double-sided substrate 1 is a double-sided FPC with copper foil and a dielectric constant of 3.4. Using a double-sided FPC with copper foil as the dielectric double-sided substrate 1 has better conductivity and stability. The choice of a material with a dielectric constant of 3.4 helps to optimize the electromagnetic performance of the antenna.

[0024] Further improvements, such as Figure 3 As shown: The reverse radiating unit 8 has seven recessed through holes 9 inside. The recessed through holes 9 help to enhance the structural strength and stability of the reverse radiating unit 8, and also help to optimize the electromagnetic field distribution of the antenna.

[0025] Further improvements, such as Figure 1 As shown: The covering ink 7 is an anti-interference black ink. Using anti-interference black ink to cover the front and back of the double-sided substrate 1 can effectively shield external electromagnetic interference and protect the antenna lines from damage.

[0026] Working principle: The dual-sided substrate carrier 1 of this utility model adopts a dual-sided FPC with copper foil on its surface and anti-interference black ink on both sides to protect the circuit from external damage. The front ink side is provided with a power supply copper leakage area 3 and a ground copper leakage area 4 for soldering coaxial cable 5. The coaxial cable 5 is soldered to the power supply and ground copper leakage areas. The other end of the coaxial cable 5 is installed with an IPEX connector 6 for quick connection with the device. By selecting the material and thickness of the dielectric substrate, ferrite is eliminated, reducing the antenna area and lowering the enterprise cost. The array is composed of positive and negative double-sided radiating units, and the frequency coverage reaches the NFC band, making it more suitable for current NFC card reading devices.
