Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an antenna and electronic equipment. Background Art

[0002] The WiFi antennas of laptops all have two antennas: the Main antenna and the Aux antenna. The locations of the WiFi antennas (Main antenna and Aux antenna) can be distributed above the LCD, in the hinge cap, and at the bottom base end according to the spatial layout of the laptop, especially the antenna located in the hinge cap.

[0003] With the rapid development of technology, various circuit systems and chips are becoming more and more integrated, which makes laptops develop towards lightness, miniaturization, and ultra-thinness, which further compresses the hinge cap space. The size and space of the antenna face great challenges. While the antenna efficiency meets the test spec, the isolation between the Main antenna and the Aux antenna is also an important indicator, especially for the WIFI 2.4GHz band. Because of its longer wavelength, the space required for its isolation is higher than that of the 5GHz band. However, the size and distance between the Main antenna and the Aux antenna are limited by the hinge cap space. This contradiction makes it difficult for the WiFi 2.4G isolation design to meet the test requirement of better than -20dB. Utility Model Content

[0026] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0027] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment.

[0028] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0029] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0030] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0031] According to an antenna of one embodiment of the present application, the antenna includes: a main antenna and an auxiliary antenna, a switch module and an isolation branch. The main antenna and the auxiliary antenna are respectively composed of multiple antenna component units. The main antenna and the auxiliary antenna both support a first working frequency band and a second working frequency band. The Pattern routing of the main antenna, the Pattern routing of the auxiliary antenna and the isolation branch are all arranged on a substrate. The switch module is arranged on the substrate between the second working frequency band Pattern routing of the main antenna or the auxiliary antenna and the isolation branch. The state of the switch module is determined based on a CPU control signal. The isolation branch is arranged on the substrate and the root of the isolation branch is close to the second working frequency band Pattern routing. When the switch module is in the first state, part of the routing of the second working frequency band Pattern and the isolation branch are enabled to jointly play an isolation role to improve the signal isolation of the antenna in the first working frequency band.

[0032] In one embodiment of the present application, when the switch module is in the second state, the isolation branch is disabled.

[0033] In one embodiment of the present application, the switch module includes a first switch and a second switch.

[0034] In one embodiment of the present application, the first switch is disposed between the second working frequency band Pattern routing and the first working frequency band Pattern routing and is close to the feeding point of the antenna assembly unit.

[0035] In one embodiment of the present application, the second switch is disposed on the substrate between the second working frequency band Pattern routing and the isolation branch.

[0036] In one embodiment of the present application, when the switch module is in the first state, some of the routing lines and isolation branches of the second working frequency band pattern are enabled to jointly play an isolation role, including: the first switch is disconnected and the second switch is turned on, the isolation branch is in an enabled state, and some of the routing lines and isolation branches of the second working frequency band pattern jointly play an isolation role.

[0037] In one embodiment of the present application, when the switch module is in the second state, the isolation branch is disabled, including: the first switch is turned on and the second switch is turned off, and the isolation branch is in a disabled state.

[0038] In one embodiment of the present application, the isolation branch is an L-shaped branch, which extends out of the antenna component unit away from the root of the L-shaped branch.

[0039] The present application also provides an electronic device, which includes any of the above antennas.

[0040] In one embodiment of the present application, the electronic device automatically detects the working frequency band of the current wireless network and generates a CPU control signal.

[0041] Figure 1 This is an antenna according to another embodiment of the present application, and is described by taking the switch module being arranged on the main antenna as an example. Figure 1 As shown, an antenna component unit is used as an example for explanation, and the antenna includes: a main antenna (not shown) and an auxiliary antenna (not shown), a switch module composed of a switch S1 and a switch S2, and an isolation branch 1001. Both the main antenna and the auxiliary antenna support the first working frequency band and the second working frequency band, and the main antenna and the auxiliary antenna respectively include a pattern routing 1002 of the first working frequency band and a pattern routing 1003 of the second working frequency band. The isolation branch 1001 is arranged on the substrate, and the root of the isolation branch 1001 is close to the second working frequency band pattern routing 1003. The switch module is arranged on the substrate between the second working frequency band pattern routing 1003 of the main antenna or the auxiliary antenna and the isolation branch 1001, and the state of the switch module is determined based on the CPU control signal; when the switch module is in the first state, part of the routing of the second working frequency band pattern and the isolation branch 1001 are enabled to play an isolation role together, so as to improve the signal isolation of the antenna in the first working frequency band.

[0042] Optionally, the operating frequency bands of the main antenna (also called the Main antenna) and the auxiliary antenna (also called the Aux antenna) can respectively support, for example, a first operating frequency band 2.4G and a second operating frequency band 5G. Accordingly, the main antenna and the auxiliary antenna respectively include a first operating frequency band 2.4G pattern routing and a second operating frequency band 5G pattern routing.

[0043] Optionally, the first switch S1 can be set between the second working frequency band pattern routing 1003 and the first working frequency band pattern routing 1002 and close to the feeding point of the antenna component unit, and the second switch S2 can be set on the substrate between the second working frequency band pattern routing 1003 and the isolation branch 1001.

[0044] Optionally, the isolation branch 1001 is an L-shaped branch, and the L-shaped branch away from the root extends out of the antenna component unit.

[0045] The antenna provided in the present application improves the signal isolation of the antenna in the first working frequency band by adding a switch module and reusing part of the pattern routing of part of the second working frequency band as isolation branches, and can meet the test spec-20dB, thereby improving the user's Internet experience.

[0046] The state of the switch module can be determined based on the on-off combination state of switches S1 and S2. When the first switch S1 is disconnected and the second switch S2 is turned on, the switch module is in the first state, the isolation branch is in the enabled state, and the isolation branch and part of the pattern routing of the second working frequency band together constitute the overall isolation branch to play an isolation role. When the first switch S1 is turned on and the second switch S2 is disconnected, the switch module is in the second state, and the isolation branch is in the disabled state.

[0047] The antenna provided in the present application realizes intelligent switching of the switch state through a switch module without the need for human intervention.

[0048] The antenna provided by the present application, the main antenna and the auxiliary antenna both include a pattern routing of the first working frequency band and a pattern routing of the second working frequency band. By adding an isolation branch and a switch module to any of the antennas, the pattern routing of any of the working frequency bands can be reused to save antenna space, and the signal isolation of the first working frequency band can be improved without affecting the performance of the second working frequency band. The antenna provided by the present application reuses part of the pattern routing of the second working frequency band as an isolation branch, making the antenna structure compact and saving antenna design space.

[0049] It should be noted that Figure 1 The structure in which the switch module is disposed on the main antenna is shown only as an example, and the switch module may also be disposed on the auxiliary antenna.

[0050] The present application also provides an electronic device, which may include any of the above-mentioned antennas.

[0051] According to the electronic device of at least one embodiment of the present application, the electronic device can automatically detect the working frequency band of the current wireless network and generate a CPU control signal.

[0052] As an example, the electronic device may be a laptop computer. When the operating frequency bands of the main antenna and the auxiliary antenna can respectively support the first operating frequency band 2.4G and the second operating frequency band 5G, the laptop computer automatically detects whether the current wireless network WiFi is operating in the 2.4G operating frequency band. If the WiFi is operating in the 2.4G operating frequency band, the CPU control signal controls switch S1 to be disconnected and control switch S2 to be turned on, and the antenna enables the second operating frequency band 5G pattern routing as an isolation branch, thereby improving the signal isolation between the WiFi 2.4G operating frequency band Main and Aux antennas. If the WiFi is operating in the 5G band, the CPU control signal controls switch S1 to be turned on and control switch S2 to be disconnected, disabling the second operating frequency band 5G pattern routing as an isolation branch and restoring the 5G band antenna performance.

[0053] Figure 2The antenna efficiency test data without using switch modules and isolation branches provided for this application is as follows: Figure 2 As shown, the figure shows the average gain data of the main antenna and the auxiliary antenna, as well as the data of the overall average gain of the antenna in each operating frequency band shown.

[0054] Figure 3 The antenna efficiency test data using the switch module and the isolation branch provided for this application, such as Figure 3 As shown, the figure shows the average gain data of the main antenna and the auxiliary antenna, as well as the data of the overall average gain of the antenna in each operating frequency band shown.

[0055] By comparison Figure 2 and Figure 3 From the test data comparison, it can be seen that the WiFi Main and Aux antenna efficiencies (2.4GHz and 5GHz bands) without enabling the isolation branch both meet the test specifications. After enabling the isolation branch, the Main antenna efficiency 2.4G band also meets the test specifications. Adding the isolation branch will not affect the antenna efficiency.

[0056] Figure 4 An example of antenna isolation test data without using a switch module and isolation branches provided for this application; Figure 5 The antenna isolation test data example provided for this application using the switch module and the isolation branch is combined with Figure 4 and Figure 5 From the data comparison, it can be seen that the isolation between the WiFi Main and Aux antennas without enabling the isolation branch does not meet the test specification in the 2.4GHz band, but meets the test specification in the WiFi 5GHz band. After enabling the isolation branch, the isolation between the WiFi Main and Aux antennas in the 2.4GHz band meets the test specification. This shows that adding the isolation branch has a significant improvement effect on the isolation (2.4GHz) between the WiFi Main and Aux antennas.
