[0002] With the development of mobile communication technology, mobile devices have become increasingly common in recent years, such as laptops, mobile phones, multimedia players, and other portable electronic devices with multiple functions. To meet people's needs, mobile devices typically have wireless communication capabilities. Some cover long-range wireless communication, such as mobile phones using 2G, 3G, and LTE (Long Term Evolution) systems and their respective frequency bands of 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz, and 2500MHz. Others cover short-range wireless communication, such as Wi-Fi and Bluetooth systems using the frequency bands of 2.4GHz, 5.2GHz, and 5.8GHz.

[0003] Antennas are indispensable components in the field of wireless communication. If the bandwidth of an antenna used for receiving or transmitting signals is insufficient, it can easily lead to a degradation in the communication quality of mobile devices. Therefore, designing small-sized, wide-bandwidth antenna components is an important task for antenna designers. Summary of the Invention

[0035] Figure 1 A schematic diagram of a mobile device 100 according to an embodiment of the present invention is shown. For example, the mobile device 100 may be a smartphone, a tablet computer, or a notebook computer. Figure 1 In one embodiment, the mobile device 100 includes: a housing 110, a first radiating element 120, a second radiating element 130, a third radiating element 140, a first switch element 151, and a second switch element 152. The first radiating element 120, the second radiating element 130, and the third radiating element 140 can all be made of metal, such as copper, silver, aluminum, iron, or their alloys. It must be understood that, although not shown in... Figure 1 However, the mobile device 100 may also include other components, such as a processor, a touch control panel, a speaker, a radio frequency (RF) module, or (and) a power supply module.

[0036] The housing 110 includes a back cover 114 and a sidewall 115, wherein the back cover 114 may be substantially perpendicular to the sidewall 115. A first radiating portion 120, a second radiating portion 130, and a third radiating portion 140 may all be distributed on the housing 110. For example, the first radiating portion 120, the second radiating portion 130, and the third radiating portion 140 may primarily be disposed on the sidewall 115, but are not limited thereto. In some embodiments, the housing 110 is made of a non-conductive material, wherein the first radiating portion 120, the second radiating portion 130, and the third radiating portion 140 may be formed on the housing 110 by laser direct structuring (LDS) technology. In other embodiments, the housing 110 is made of a metallic material, wherein the aforementioned first radiating portion 120, the second radiating portion 130, and the third radiating portion 140 may be integrated with the housing 110. In addition, the first radiating part 120, the second radiating part 130, and the third radiating part 140 can be attached to a plastic injection element (not shown).

[0037] The first radiating section 120 can generally be shaped like an inverted U. Specifically, the first radiating section 120 has a first end 121 and a second end 122, wherein a first feeding point FP1 is located at the first end 121 of the first radiating section 120, and the second end 122 of the first radiating section 120 is an open end. The first feeding point FP1 can also be coupled to a first signal source 191.

[0038] The second radiating section 130 may generally present another inverted U-shape. Specifically, the second radiating section 130 has a first end 131 and a second end 132, wherein a second feed point FP2 is located at the first end 131 of the second radiating section 130, and the second end 132 of the second radiating section 130 is an open-circuit end. The second feed point FP2 may further be coupled to a second signal source 192.

[0039] The third radiating section 140 may generally be M-shaped. Specifically, the third radiating section 140 has a first end 141 and a second end 142. One end of a first switch 151 is coupled to the first end 121 of the first radiating section 120, and the other end of the first switch 151 is coupled to the first end 141 of the third radiating section 140. The first switch 151 can be closed or open to selectively couple the first radiating section 120 to the third radiating section 140. One end of a second switch 152 is coupled to the first end 131 of the second radiating section 130, and the other end of the second switch 152 is coupled to the second end 142 of the third radiating section 140. The second switch 152 can be closed or open to selectively couple the second radiating section 130 to the third radiating section 140. In some embodiments, the first switch 151 and the second switch 152 may be controlled by a processor based on user input, but are not limited thereto.

[0040] It is important to note that the first radiator 120, the second radiator 130, and the third radiator 140 can form the antenna structure of the mobile device 100. By controlling the on or off states of the first switch 151 and the second switch 152, the length of the resonant path of this antenna structure can be adjusted, so that the antenna structure of the mobile device 100 can cover multiple frequency bands. Since the first radiator 120, the second radiator 130, and the third radiator 140 can be appropriately integrated with the housing 110, the overall size of the antenna structure of the mobile device 100 can be further miniaturized. In addition, because the first feed point FP1 and the second feed point FP2 are used simultaneously, the mobile device 100 can also support multiple-input multiple-output (MIMO) operation.

[0041] The following examples will illustrate various configurations and detailed structural features of mobile devices. It must be understood that these figures and descriptions are merely illustrative and not intended to limit the scope of the invention.

[0042] Figure 2 A schematic diagram of a mobile device 200 according to an embodiment of the present invention is shown. Figure 2 and Figure 1 Similar. Figure 2In one embodiment, a third radiating section 240 of the mobile device 200 includes a first segment 244 and a second segment 245, wherein the first segment 244 is coupled to a first switch 151, and the second segment 245 is coupled to a second switch 152. For example, the first segment 244 and the second segment 245 may each generally present an inverted U-shape, but are not limited thereto. Furthermore, the mobile device 200 further includes a third switch 153, wherein one end of the third switch 153 is coupled to the first segment 244, and the other end of the third switch 153 is coupled to the second segment 245. The third switch 153 can be turned on or off to selectively couple the first segment 244 to the second segment 245. As described above, by controlling the first switch 151, the second switch 152, and the third switch 153 to adjust the length of the equivalent resonant path, the antenna structure of the mobile device 200 can cover a wider operating frequency band. In some embodiments, the mobile device 200 further includes a dielectric substrate 260, which may be an FR4 (Flame Retardant 4) substrate or a printed circuit board (PCB). The first switch 151, the second switch 152, the third switch 153, the first signal source 191, and the second signal source 192 may all be disposed on this dielectric substrate 260. In other embodiments, the first radiating portion 120, the second radiating portion 130, and the third radiating portion 240 may also be at least partially disposed on the dielectric substrate 260 to facilitate mutual coupling with the first switch 151, the second switch 152, the third switch 153, the first signal source 191, and the second signal source 192. Figure 2 The remaining features of the mobile device 200 are all the same Figure 1 Since the mobile device 100 is similar, both embodiments can achieve similar operational effects.

[0043] Figure 3 A schematic diagram of a mobile device 300 according to an embodiment of the present invention is shown. Figure 3 and Figure 1 Similar. Figure 3In one embodiment, the mobile device 300 includes: a housing 310, a first radiating portion 320, a second radiating portion 330, a third radiating portion 340, a first switch 151, a second switch 152, a third switch 153, and a dielectric substrate 260. For example, the housing 310 may be made of a non-conductive material and may include a back cover 314 and a sidewall 315. The sidewall 315 has a plurality of openings 371, 372, 373, 374, 375, 376, 377, 378, and 379, all of which may be arranged on the same straight line. For example, the aforementioned openings 371, 372, 373, 374, 375, 376, 377, 378, and 379 may each be approximately circular, elliptical, or square. In some embodiments, the aforementioned openings 371, 372, 373, 374, 375, 376, 377, 378, and 379 may be speaker openings or microphone openings, but are not limited thereto. It must be understood that the number and configuration of the aforementioned openings 371, 372, 373, 374, 375, 376, 377, 378, and 379 can also be adjusted according to different needs.

[0044] The first radiating portion 320 may generally have a meandering shape, which may be staggered with the openings 371 and 372 of the sidewall 315. Specifically, the first radiating portion 320 has a first end 321 and a second end 322, wherein a first feed point FP1 is located at the first end 321 of the first radiating portion 320, and the second end 322 of the first radiating portion 320 is an open-circuit end. The second radiating portion 330 may generally have another meandering shape, which may be staggered with the openings 378 and 379 of the sidewall 315. Specifically, the second radiating portion 330 has a first end 331 and a second end 332, wherein a second feed point FP2 is located at the first end 331 of the second radiating portion 330, and the second end 332 of the second radiating portion 330 is an open-circuit end. For example, the second end 332 of the second radiating portion 330 and the second end 322 of the first radiating portion 320 may extend in generally opposite and mutually distant directions.

[0045] The third radiating section 340 can generally be M-shaped, and it can be arranged alternately with the openings 373, 374, 375, 376, and 377 of the sidewall 315. Specifically, the third radiating section 340 has a first end 341 and a second end 342, and includes a first segment 344 adjacent to the first end 341 and a second segment 345 adjacent to the second end 342, wherein the first segment 344 at least partially surrounds the opening 374, the second segment 345 at least partially surrounds the opening 376, and the opening 375 is located between the first segment 344 and the second segment 345. One end of the first switcher 151 is coupled to the first end 321 of the first radiating section 320, and the other end of the first switcher 151 is coupled to the first segment 344. One end of the second switcher 152 is coupled to the first end 331 of the second radiating section 330, and the other end of the second switcher 152 is coupled to the second segment 345. One end of the third switch 153 is coupled to the first segment 344, while the other end of the third switch 153 is coupled to the second segment 345.

[0046] In some embodiments, by controlling the on / off states of the first switch 151, the second switch 152, and the third switch 153, the antenna structure of the mobile device 100 can cover multiple frequency bands. Specifically, when all three switches are on, the antenna structure with the longest resonant length can simultaneously cover a first frequency band, a second frequency band, a third frequency band, and a fourth frequency band. When only two of the three switches are on (e.g., both the first and third switches are on, but the second switch is off), the antenna structure will only cover the aforementioned second, third, and fourth frequency bands. When only one of the first switch 151, the second switch 152, and the third switch 153 is turned on (e.g., the first switch 151 is turned on, but the second switch 152 and the third switch 153 are both turned off), the antenna structure will only cover the aforementioned third and fourth frequency bands. When the first switch 151, the second switch 152, and the third switch 153 are all turned off, the antenna structure with the shortest resonant length will only cover the aforementioned fourth frequency band. It should be noted that any unused radiating element can also be used to increase the isolation between other radiating elements. For example, the aforementioned first frequency band may be between 600MHz and 1000MHz, the aforementioned second frequency band may be between 1400MHz and 2700MHz, the aforementioned third frequency band may be between 3200MHz and 5000MHz, and the aforementioned fourth frequency band may be between 5000MHz and 7200MHz. Therefore, the antenna structure of the mobile device 300 will be able to support broadband operation of next-generation 5G (5th Generation Wireless Systems). However, the invention is not limited thereto. In other embodiments, the antenna structure of the mobile device 300 may also cover the operating frequency bands of LTE (Long Term Evolution), GPS (Global Positioning System), or Wi-Fi 6E. Figure 3 The remaining features of the mobile device 300 are all the same Figure 1 Since the mobile device 100 is similar, both embodiments can achieve similar operational effects.

[0047] Figure 4 A schematic diagram of a mobile device 400 according to an embodiment of the present invention is shown. Figure 4 and Figure 3 Similar. Figure 4In some embodiments, the first segment 344 or the second segment 345 of the third radiating section 340 further has a third feed point FP3, which can be coupled to a third signal source 193, enabling the mobile device 400 to support more complex multiple-input multiple-output operations. Additionally, with Figure 3 In comparison, the lengths of the first radiating section 320 and the second radiating section 330 are further extended. Based on different usage requirements, the mobile device 400 can also have more feed points and be equipped with more switchers and more signal sources. Figure 4 The remaining features of the mobile device 400 are all the same Figure 3 The mobile device 300 is similar, so both embodiments can achieve similar operational effects.

[0048] Figure 5 A schematic diagram of a mobile device 500 according to an embodiment of the present invention is shown. Figure 5 and Figure 4 Similar. Figure 5 In one embodiment, a first radiating portion 520 of the mobile device 500 includes an H-shaped portion 527, a second radiating portion 530 includes a C-shaped portion 537, and a third radiating portion 540 includes a T-shaped portion 547. It should be noted that the aforementioned H-shaped portion 527, C-shaped portion 537, and T-shaped portion 547 can all extend to the outer surface of the sidewall 315, so the user can directly observe the "HTC" trademark on the mobile device 500. In other words, the irregularly designed first radiating portion 520, second radiating portion 530, and third radiating portion 540 not only generate the radiation field pattern of the antenna structure, but also enhance the appearance of the mobile device 500. In other embodiments, the first radiating portion 520, second radiating portion 530, and third radiating portion 540 can also be used to display other different styles of text, patterns, or trademarks, but are not limited to these. Figure 5 The remaining features of the mobile device 500 are all the same Figure 4 The mobile device 400 is similar, so both embodiments can achieve similar operational effects.

[0049] This invention proposes a novel mobile device that may include an antenna structure. Compared with conventional designs, this invention has advantages such as small size, wide bandwidth, and low manufacturing cost, making it well-suited for application in a wide variety of mobile communication devices.

[0050] It is worth noting that the component dimensions, shapes, and frequency ranges described above are not limiting factors of this invention. Designers can adjust these settings according to different needs. The antenna structure of this invention is not limited to... Figure 1-5 The state shown. This invention may include only... Figure 1-5Any one or more features of any one or more embodiments. In other words, not all the features illustrated need to be implemented simultaneously in the antenna structure of the present invention.
