[0002] With the development of 5G communication, in order to expand the frequency and bandwidth used by WIFI, the WIFI6E antenna was designed accordingly. Compared with the traditional WIFI6 antenna, the WIFI6E antenna adds the 6GHz band (5925MHz to 7125MHz) to the traditional 2.4G band (2400MHz to 2500MHz) and 5G band (5150MHz to 5850MHz).

[0003] The increased antenna operating bandwidth makes antenna debugging more difficult and increases the likelihood of interference between multiple operating frequency bands, leading to a decrease in antenna communication quality. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0019] The first embodiment of this utility model relates to a WIFI 6E antenna, such as Figure 1 As shown, the WIFI6E antenna includes: a feeding unit 1, an isolation unit 3, and a first antenna unit 21 and a second antenna unit 22 arranged mirror-symmetrically with respect to the isolation unit 3; the first antenna unit 21 and the second antenna unit 22 are respectively connected to the corresponding feeding unit 1; the first antenna unit 21 includes: a first branch 201, a second branch 202 and a third branch 203 arranged sequentially toward the isolation unit 3; the second antenna unit 22 includes: a fourth branch 204, a fifth branch 205 and a sixth branch 206 arranged sequentially toward the isolation unit; wherein, the center frequencies of the first branch 201 and the fourth branch 204 are the same, the center frequencies of the second branch 202 and the fifth branch 205 are the same, and the center frequencies of the third branch 203 and the sixth branch 206 are the same; the isolation unit 3 is grounded, and the isolation unit 3 is used to isolate the target electromagnetic waves between the first antenna unit 21 and the second antenna unit 22.

[0020] The target electromagnetic wave here can be understood as the electromagnetic wave generated by the coupling between the first and second antenna elements due to their proximity. The isolation unit effectively improves the overall performance of the antenna by isolating the target electromagnetic wave.

[0021] The lengths of each branch in the first and second antenna elements are related to their operating frequencies, and can be set to one-quarter of the wavelength corresponding to the operating frequency. In this embodiment, since the first antenna element includes a first branch, a second branch, and a third branch, the coupling between these branches can affect the operating frequency. To ensure that the operating frequency meets the preset requirements, the lengths of each branch need to be fine-tuned. That is, the length value is taken as one-quarter of the wavelength as a reference value, and the resonant frequency of each branch is adjusted by fluctuating around the reference value until the resonant frequency of each branch meets its operating frequency. Similarly, the fourth, fifth, and sixth branches of the second antenna element are adjusted in the same way to meet the corresponding operating frequency requirements.

[0022] Since the WIFI 6E antenna needs to resonate in the 2.4G, 5G, and 6G frequency bands, in this embodiment, the three branches of the first antenna unit respectively satisfy the resonance requirements of the 2.4G, 5G, and 6G frequency bands. Correspondingly, the three branches of the second antenna unit also need to satisfy the resonance requirements of the 2.4G, 5G, and 6G frequency bands. Because the first and second antenna units are mirror-symmetrically arranged, the center frequencies of the first and fourth branches are the same, the center frequencies of the second and fifth branches are the same, and the center frequencies of the third and sixth branches are the same. Taking a center frequency of 6G for the first and fourth branches, 2.4G for the second and fifth branches, and 5G for the third and sixth branches as an example, the lengths of the branches of the first antenna unit are: the length of the first branch is less than the length of the third branch, which is less than the length of the second branch. The lengths of the branches of the second antenna unit are: the length of the fourth branch is less than the length of the sixth branch, which is less than the length of the fifth branch.

[0023] Furthermore, both the first and fourth branches are parasitic. The first branch is excited through coupling with the second and third branches, while the fourth branch is excited through coupling with the fifth and sixth branches. With both the first and fourth branches being parasitic, their operating frequency bands can be configured to the 6GHz band. Since higher operating frequencies result in shorter branch lengths, the coupling-excitation method of parasitic branches is more conducive to miniaturizing branch size.

[0024] The third branch is directly connected to the power supply unit, and the second branch is formed by extending the third branch. There are two power supply units, which are respectively set on both sides of the isolation unit. One power supply unit is connected to the third branch, and the other power supply unit is directly connected to the sixth branch. The fifth branch is formed by extending the sixth branch.

[0025] The operating frequency range of each of the above branches meets the standard of WIFI6E antenna. For example, the frequency range corresponding to the first and fourth branches is 5.925GHz to 7.125GHz; the frequency range corresponding to the second and fifth branches is 2.400GHz to 2.495GHz; and the frequency range corresponding to the third and sixth branches is 5.150GHz to 5.895GHz.

[0026] Compared to related technologies, this solution's Wi-Fi 6E antenna includes: a feed unit, an isolation unit, and a first and second antenna unit arranged symmetrically in mirror image of the isolation unit. The first and second antenna units each have multiple branches to satisfy the resonance of multiple frequency bands of the Wi-Fi 6E antenna, such as the 2.4GHz, 5GHz, and 6GHz bands, thus widening the antenna bandwidth. Furthermore, the mirrored design of the dual-antenna structure of the first and second antenna units allows for more uniform signal coverage. The isolation unit is grounded and is used to isolate target electromagnetic waves between the first and second antenna units, effectively isolating interference between them and improving the communication quality of the dual-antenna structure.

[0027] The second embodiment of this utility model relates to a WIFI6E antenna. Compared with the first embodiment, the specific structure of the isolation unit is described in this embodiment.

[0028] like Figure 2 As shown, the isolation unit includes: a seventh branch 307 near the first antenna element, an eighth branch 308 near the second antenna element, and a ninth branch 309 between the seventh branch 307 and the eighth branch 308; the seventh branch 307, the eighth branch 308 and the ninth branch 309 are coupled with the first antenna element to obtain a first signal, and the seventh branch 307, the eighth branch 308 and the ninth branch 309 are coupled with the second antenna element to obtain a second signal. The first signal and the second signal are out of phase, thus canceling each other out, thereby reducing the interference between the first antenna element and the second antenna element.

[0029] The seventh, eighth, and ninth branches are positioned around the main ground plane and can be configured to isolate interference at different frequencies. For example, the seventh branch can be configured to isolate interference in the 2.4 GHz band, the eighth branch to isolate interference in the 6 GHz band, and the ninth branch to isolate interference in the 5 GHz band. Furthermore, the interference signals generated by the seventh and eighth branches are isolated, improving the overall isolation effect of the isolation unit on the two antenna structures.

[0030] The seventh, eighth, and ninth branches are all parasitic coupling stubs. By adjusting the length of each branch, their isolation of interference signals in different frequency bands can be controlled.

[0031] In this embodiment, by setting each branch in the isolation unit, the isolation of the isolation unit for the dual-antenna structure is improved, and the mutual influence between the first antenna unit and the second antenna unit is reduced.

[0032] In the above embodiments, the WIFI6E antenna can be configured to meet the size specifications of different products. For example, when applying the WIFI6E antenna to a Dongle product, to meet the size requirements of the Dongle product, the size of the area where the isolation unit, the first antenna unit, and the second antenna unit are located can be 23 mm × 25 mm. This configuration of the WIFI6E antenna will not affect the configuration of other components in the Dongle product and will not additionally affect the size specifications of the Dongle product. Under this size specification requirement, the width of both the first and second antenna units of the WIFI6E antenna is 8 mm, and the width of the isolation unit is 7 mm; wherein the direction of the width is consistent with the arrangement direction of the first antenna unit, the isolation unit, and the second antenna unit.

[0033] The third embodiment of this utility model relates to a communication device, such as... Figure 3 As shown, the communication device includes the aforementioned WIFI6E antenna 10 and chipset 20.

[0034] In this embodiment, the communication device can be a Dongle product. A Dongle product is a small hardware device, typically connected via a USB interface, used to implement functions such as wireless communication, software licensing, encryption, or network access. It is widely used in Bluetooth devices, industrial control, drones, and other fields. The Dongle product with a built-in Wi-Fi 6E antenna in this application can achieve wireless communication functionality. The chipset can at least implement the functions of a radio frequency front-end, for example, amplifying the radio frequency signal sent by the baseband processor to a sufficient power so that the Wi-Fi 6E antenna can effectively radiate the signal.

[0035] Compared with related technologies, the communication device provided in this utility model embodiment is equipped with the WIFI6E antenna provided in the aforementioned embodiment. Therefore, it also has the technical effects provided in the aforementioned embodiment, which will not be elaborated here.

[0036] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
