[0060] To provide a more detailed and complete description of the invention, reference can be made to the accompanying drawings and the various embodiments described below, in which the same numbers represent the same or similar elements. Furthermore, well-known elements and steps are not described in the embodiments to avoid unnecessarily limiting the invention.

[0061] Please refer to Figure 1 The present invention provides an antenna device 110, which is applicable to various electronic devices 100 with wireless communication functions, or widely used in related technical aspects. The antenna device 110 of this embodiment achieves considerable technical advancement and has broad industrial application value. The following will be accompanied by... Figure 1 , Figure 2 , Figure 3 This will illustrate the specific implementation of the antenna device 110.

[0062] It should be understood that the antenna device 110 can be implemented in various ways. Figure 1 , Figure 2 , Figure 3 The following description provides a comprehensive account of one or more embodiments for ease of explanation. However, the technology can be practiced without these specific details. In other examples, known structures and apparatuses are shown in block diagram form for the effective description of these embodiments. The term "by way of example" is used herein to mean "as an example, instance, or illustration." Any embodiment described herein as "by way of example" should not be construed as preferred or superior to other embodiments.

[0063] Please refer to Figure 1 , Figure 1 This is a plan view of an electronic device 100 according to some embodiments of the present invention. In practice, for example, the electronic device 100 may be adapted to a laptop computer, screen, mobile phone, tablet computer or other electronic product.

[0064] like Figure 1As shown, the electronic device 100 includes an antenna device 110, a radio frequency module 120, and a display panel 130. Architecturally, the antenna device 110 is disposed around the display panel 130, and the radio frequency module 120 is disposed on a substrate below the display panel 130.

[0065] In some embodiments of the present invention, the antenna device 110 integrates a microstrip line filter and an antenna, and the output terminal 112 of the antenna device 110 is electrically connected to the radio frequency module 120. In a control experiment, the antenna is connected to an external filter on a substrate through one set of lines, and the external filter is then connected to the radio frequency module through another set of lines. This results in additional losses, and the external filter and its substrate occupy additional space and have high assembly costs. Compared to the aforementioned control experiment, the antenna device 110 of the present invention integrates the microstrip line filter and the antenna together, which saves substrate and filter space, has advantages in space utilization, reduces costs, simplifies circuit design during the R&D stage, and simplifies assembly in the factory, reducing assembly time and costs.

[0066] It should be understood that in the embodiments and claims, the description involving "electrical connection" can generally refer to one element being indirectly electrically coupled to another element through other elements, or one element being directly electrically connected to another element without needing to go through other elements. For example, the output terminal 112 of the antenna device 110 can be directly and physically connected to the radio frequency module 120, or the output terminal 112 of the antenna device 110 can be indirectly electrically coupled to the radio frequency module 120 through a line.

[0067] In practice, considering antenna efficiency, in some embodiments of the present invention, the display panel surface 113 of the antenna device 110 may not be designed with an antenna, but is used to configure a microstrip line filter. The display panel surface 113 of the antenna device 110 and the display panel 130 face the same direction. The display panel surface 113 can be covered by the frame of the electronic device 100. The display panel surface 113 of the antenna device 110 is approximately perpendicular to the top cover 115 of the antenna device 110.

[0068] As used herein, “about,” “approximately,” or “roughly” are used to modify any quantity that may vary slightly, but such slight variation does not change its nature. Unless otherwise specified in the embodiments, the error range of the values ​​modified by “about,” “approximately,” or “roughly” is generally permissible within 20 percent, preferably within 10 percent, and more preferably within 5 percent.

[0069] To further explain the configuration of the microstrip line filter in the antenna device 110, please refer to Figures 1 and 2. Figure 2 This is a perspective view of an antenna device 110 according to some embodiments of the present invention from a first viewing angle. Figure 2As shown, the antenna device 110 includes an antenna pattern 210 and a microstrip line filter 220. Architecturally, the microstrip line filter 220 is disposed on the display panel surface 113 and is electrically connected to the antenna pattern 210.

[0070] In some embodiments of the present invention, the antenna device 110 further includes a lead-out terminal 112. Architecturally, the lead-out terminal 112 is electrically connected to the microstrip line filter 220.

[0071] Regarding the architecture of antenna pattern 210, in some embodiments of the present invention, antenna pattern 210 includes a first antenna pattern 211 (e.g., a first antenna metal pattern layer). Architecturally, one side of the upper cover 115 is connected to the display panel surface 113, and the first antenna pattern 211 is disposed on the upper cover 115, providing better antenna performance and being located away from... Figure 1 Interference with the display panel 130.

[0072] To further illustrate the configuration of the antenna pattern 210 described above, please also refer to... Figure 1 , Figure 2 , Figure 3 . Figure 3 This is a perspective view of an antenna device 110 according to some embodiments of the present invention from a second viewing angle. Figure 3 As shown, the other side of the top cover 115 connects to the back cover 316. Figure 3 316 and the back cover Figure 2 The display panel surfaces 113 are opposite to each other. Antenna pattern 210 also includes a second antenna pattern 312 (e.g., a second antenna metallic pattern layer). Architecturally, the second antenna pattern 312 is positioned at the back cover 316, providing better antenna performance and being located away from the antenna. Figure 1 Interference with the display panel 130.

[0073] It should be understood that in the embodiments and claims, descriptions involving "first", "second", etc. are used to avoid confusion between elements, and the terms do not limit the number or quality of elements.

[0074] In summary, please also refer to the above. Figure 1 , Figure 2 , Figure 3 In some embodiments of the present invention, the antenna device 110 may include an antenna pattern 210, a microstrip line filter 220, and a lead-out terminal 112. Architecturally, the antenna pattern 210 is disposed at at least one of the upper cover 115 and the back cover 316. The microstrip line filter 220 is disposed on the display panel surface 113, with one end of the microstrip line filter 220 electrically connected to the antenna pattern 210, and the lead-out terminal 112 electrically connected to the other end of the microstrip line filter 220. The back cover 316 and the display panel surface 113 are located on opposite sides of the upper cover 115.

[0075] To further explain the structure of the microstrip line filter 220 described above, please refer to [link / reference needed]. Figure 2 .like Figure 2 As shown, in some embodiments of the present invention, the microstrip line filter 220 includes a plurality of strip microstrip lines 221 to 225. Architecturally, the plurality of strip microstrip lines 221 to 225 are arranged at intervals on the display panel surface 113, and each of the plurality of strip microstrip lines 221 to 225 has at least a portion located beside at least a portion of an adjacent portion of the plurality of microstrip lines.

[0076] For example, a portion of strip microstrip line 221 is located beside a portion of strip microstrip line 222, another portion of strip microstrip line 222 is located beside a portion of strip microstrip line 223, another portion of strip microstrip line 223 is located beside a portion of strip microstrip line 224, and another portion of strip microstrip line 224 is located beside a portion of strip microstrip line 225. One end of strip microstrip line 221 is electrically connected to antenna pattern 210, and one end of strip microstrip line 225 is electrically connected to output terminal 112.

[0077] To achieve the design of the microstrip filter 220, the traditional filter composed of inductors and capacitors needs to be replaced with microstrip lines (e.g., strip microstrip lines 221-225).

[0078] Microstrip line inductance can be achieved by designing microstrip lines of appropriate length and width. The inductance value (L) is related to the length (l) of the microstrip line and its characteristic impedance (Zo). The formula for calculating the inductance value is: L = Zo × l / c, where c is the speed of light.

[0079] Microstrip line capacitance can be achieved by designing parallel microstrip lines with appropriate spacing and length. The capacitance value (C) is related to the spacing (d) and length (l) of the microstrip lines. The formula for calculating the capacitance value is: C = ε r ×ε o ×l / d, where ε r ε is the dielectric constant. o The permittivity is given by the value of ν in a vacuum.

[0080] In practice, for example, the microstrip filter 220 can be implemented directly on a flexible printed circuit board (FPC) without the need for additional resistors, inductors, and / or capacitors, thus incurring no additional manufacturing costs. The filter function is achieved by varying the impedance of the transmission lines (e.g., strip microstrip lines 221-225).
