(See diagram for example.) Figure 3 As shown, a circuit board P is provided inside the aforementioned housing H, wherein the position of the circuit board P corresponds to a slot pattern D on the housing H; specifically, the aforementioned circuit board P is disposed inside the housing H and is located below the first slot D1 and the second slot D2, that is, the first slot D1 and the second slot D2 at least partially overlap with the circuit board P in the Z-axis direction (vertical direction), wherein the aforementioned circuit board P has a third length L3 in the X-axis direction, and the aforementioned third length L3 is approximately 50 mm.

[0068] In addition, from Figure 3 As can be seen from the above, the first slot D1 and the second slot D2 both have a first width W1 in the Y-axis direction, and the circuit board P has a second width W2 in the Y-axis direction. The first slot D1 and the second slot D2 are located at the center of the circuit board P in the Y-axis direction.

[0069] In one embodiment, the aforementioned first width W1 is approximately 1.6 mm, and the aforementioned second width W2 is approximately 8 mm.

[0070] Please refer to the following: Figure 4 ,in Figure 4 express Figure 3 The circuit board P in the diagram includes a schematic of a first antenna structure A and a second antenna structure B.

In addition, a ground point E2 is provided on the base section B2, which can be electrically connected to a large area of ​​copper foil grounding structure to achieve the function of grounding.

[0074] Please refer to the following: Figure 5 ,in Figure 5 express Figure 4 A schematic diagram showing the dimensions of each component on circuit board P. (See attached diagram.) Figure 5As shown, the first conductive portion A1 of the aforementioned first antenna structure A has a fourth length L4 in the X-axis direction, and the second conductive portion A2 of the aforementioned first antenna structure A has a fifth length L5 in the X-axis direction; furthermore, the microstrip line portion B1 of the aforementioned second antenna structure B has a sixth length L6 in the X-axis direction, and the base portion B2 of the aforementioned second antenna structure B has a seventh length L7 in the X-axis direction. Also, a fourth gap d4 is formed between the second conductive portion A2 of the aforementioned first antenna structure A1 and the base portion B2 of the aforementioned second antenna structure B in the X-axis direction.

[0075] In one embodiment, the aforementioned fourth length L4 is approximately 20 mm, the aforementioned fifth length L5 is approximately 7 mm, the aforementioned sixth length L6 is approximately 20 mm, the aforementioned seventh length L7 is approximately 22 mm, and the aforementioned fourth gap d4 is approximately 1 mm.

[0076] In other words, the length of the base B2 of the second antenna structure B in the long axis direction (X-axis direction) of the circuit board P is greater than the length of the microstrip line B1 in the long axis direction (X-axis direction) of the circuit board P, and the second conductive part A2 and the base B2 of the second antenna structure B are about 1 mm apart in the long axis direction (X-axis direction) of the circuit board P.

[0077] In addition, from Figure 5 As can be seen from the above, the first conductive part A1 has a third width W3 in the Y-axis direction, the third conductive part A3 and the fourth conductive part A4 together have a fourth width W4 in the Y-axis direction, and the bottom of the fourth conductive part A4 has a fifth width W5.

The microstrip line part B1 of the second slot D2 does not overlap with the first slot D1 or the second slot D2 in the Z-axis direction, and this vertical direction is perpendicular to the circuit board P.

[0082] In this embodiment, through the aforementioned configuration, different coupling variations can be achieved between the first slot D1 and the first, second, third, and fourth conductive parts A1, A2, A3, and A4 in the first antenna structure A, as well as the base B2 in the second antenna structure B, thereby generating a resonance to achieve a dual-band effect of 2.4GHz / 5GHz. On the other hand, the second slot D2 can also generate different coupling variations between the microstrip line part B1 and the base B2 in the second antenna structure B. Furthermore, the microstrip line part B1 and the base B2 in the second antenna structure B can also couple with each other, thereby generating a resonance to achieve a high-frequency effect of 6GHz, enabling the electronic device to realize tri-band (2.4GHz / 5GHz / 6GHz) wireless communication functions.
