[0002] With the advancement of mobile communication technology, mobile devices have become increasingly common in recent years. Common examples include laptops, mobile phones, multimedia players, and other hybrid portable electronic devices. To meet people's needs, mobile devices often include wireless communication capabilities. Some cover long-range wireless communication, such as mobile phones using 2G, 3G, and LTE (Long Term Evolution) systems and their use of 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 2.4GHz, 5.2GHz, and 5.8GHz frequency bands.

[0003] Antennas are essential components in wireless communications. If the operating bandwidth of an antenna used to receive or transmit signals is too narrow, communication quality can be degraded in mobile devices. Therefore, designing a compact, broadband antenna structure is a crucial challenge for designers. Utility Model Content

[0058] The ground element 110 may be substantially irregular in shape. The ground element 110 is coupled to a ground voltage VSS. In some embodiments, the ground voltage VSS may be provided by a system ground plane (not shown).

[0059] The feed radiating portion 120 can be substantially in the shape of a straight strip. Specifically, the feed radiating portion 120 has a first end 121 and a second end 122, wherein a feeding point FP is located at the first end 121 of the feed radiating portion 120. The feeding point FP can be further coupled to a positive electrode (positive electrode) of a signal source (not shown), and a negative electrode (negative electrode) of the signal source can be coupled to the ground component 110.

The first end 131 of the connecting radiating portion 130 is coupled to the ground element 110, while the second end 132 of the connecting radiating portion 130 is coupled to the second end 122 of the feeding radiating portion 120. In other words, the feeding radiating portion 120 can be coupled to the ground element 110 via the connecting radiating portion 130.

It should be noted that the term "adjacent" or "adjacent" in this specification may refer to a situation where the distance between the two corresponding components is less than a predetermined distance (e.g., 10 mm or less), and may also include a situation where the two corresponding components are in direct contact with each other (i.e., the aforementioned distance is shortened to 0).

[0063] The first radiating portion 150 can be generally shaped like a figure 7. Specifically, the first radiating portion 150 has a first end 151 and a second end 152. The first end 151 of the first radiating portion 150 is coupled to the conductive via 140, while the second end 152 of the first radiating portion 150 is an open end. In some embodiments, the connecting radiating portion 130 has a vertical projection on the second surface E2 of the non-conductive support element 190, where this vertical projection can at least partially overlap with the first radiating portion 150.

[0064] The second radiating portion 160 can be roughly pentagonal. Specifically, the second radiating portion 160 has a first end 161 and a second end 162. The first end 161 of the second radiating portion 160 is coupled to the conductive via 140, while the second end 162 of the second radiating portion 160 is open. Furthermore, the second radiating portion 160 can be coupled to both the first radiating portion 150 and the third radiating portion 170.

For example, the protruding portion 165 of the second radiating portion 160 can be roughly rectangular. In some embodiments, a slot 180 can be formed between the first radiating portion 150 and the second radiating portion 160. For example, the slot 180 can be a monopole slot having a closed end 181 and an open end 182.

[0065] The third radiating portion 170 can be substantially in the shape of another straight strip and can be substantially perpendicular to the feed radiating portion 120. Specifically, the third radiating portion 170 has a first end 171 and a second end 172. The first end 171 of the third radiating portion 170 is coupled to the conductive via 140, while the second end 172 of the third radiating portion 170 is open and adjacent to the protruding portion 165 of the second radiating portion 160. In some embodiments, at least a portion of the third radiating portion 170 and the first radiating portion 150 can be located on the same straight line.

[0066] Figure 4 The figure shows the voltage standing wave ratio (VSWR) of the antenna structure 100 according to an embodiment of the present invention, wherein the horizontal axis represents the operating frequency (MHz) and the vertical axis represents the voltage standing wave ratio. Figure 4 Based on the measurement results, the antenna structure 100 can cover a first frequency band (FB1), a second frequency band (FB2), and a third frequency band (FB3). For example, the first frequency band (FB1) can be between 2400MHz and 2500MHz, the second frequency band (FB2) can be between 5150MHz and 5850MHz, and the third frequency band (FB3) can be between 5925MHz and 7125MHz. Therefore, the antenna structure 100 can support at least WLAN (Wireless Local Area Network), Wi-Fi 6E, and Wi-Fi 7 broadband operations.

[0067] In some embodiments, the operating principles of the antenna structure 100 can be described as follows.

The feed radiating element 120, the conductive via 140, and the third radiating element 170 can generate the aforementioned third frequency band FB3. A coupling mechanism is generated between the connecting radiating element 130 and the first radiating element 150, thereby fine-tuning the impedance matching between the first frequency band FB1 and the third frequency band FB3. Furthermore, the protruding portion 165 of the second radiating element 160 can be used to fine-tune the impedance matching of the aforementioned second frequency band FB2.

[0068] In some embodiments, the component dimensions of the antenna structure 100 may be as follows. The combined length L1 of the feed radiating portion 120 and the first radiating portion 150 may be approximately equal to 0.25 times the wavelength (λ / 4) of the first frequency band FB1 of the antenna structure 100. The combined length L2 of the feed radiating portion 120 and the second radiating portion 160 may be approximately equal to 0.25 times the wavelength (λ / 4) of the second frequency band FB2 of the antenna structure 100. The combined length L3 of the feed radiating portion 120 and the third radiating portion 170 may be approximately equal to 0.25 times the wavelength (λ / 4) of the third frequency band FB3 of the antenna structure 100. The length L4 of the connecting radiating portion 130 may be between 10 mm and 14 mm. The length L5 of the protruding portion 165 of the second radiating portion 160 may be between 4 mm and 6 mm. The thickness H1 of the non-conductive support member 190 may be between 0.5 mm and 1.5 mm. The above component size ranges are obtained based on multiple experimental results, which help optimize the operational bandwidth and impedance matching of the antenna structure 100 .

[0069] In some embodiments, the antenna structure 100 can be implemented in a point-of-sale (POS) system (not shown). Because the POS system includes the antenna structure 100, it can support wireless communication. In some embodiments, the POS system further includes, but is not limited to, an RF circuit, a filter, an amplifier, a processor, or a housing.

[0070] The present invention proposes a novel antenna structure. Compared with conventional designs, the present invention has advantages such as small size, wide bandwidth, and low manufacturing cost, making it suitable for application in various mobile communication devices or the Internet of Things.

[0071] It is worth noting that the above-mentioned component size, component shape, and frequency range are not the limitations of the present invention. Antenna designers can adjust these settings according to different needs. The antenna structure of the present invention is not limited to Figure 1-4 The utility model may only include Figure 1-4 Any one or more features of any one or more embodiments of the drawings. In other words, not all features of the drawings need to be implemented in the antenna structure of the present invention at the same time.

[0072] In this specification and claims, ordinal numbers, such as "first", "second", "third", etc., have no sequential relationship with each other and are only used to distinguish two different components with the same name.
