Description

When multiple communication technologies need to be implemented on one terminal, correspondingly, multiple antennas need to be designed on the terminal device.
[0003] Taking a notebook computer including Wireless Wide Area Network (WWAN) and Wireless Local Area Network (WLAN) communications as an example. In the existing antenna design scheme, the antennas connected to the WWAN card and the WLAN card are both independently designed and developed; among them, there are a total of 4 antenna structures for the antennas connected to the WWAN card, including WWAN main set, WWAN diversity, WWAN MIMO (Multiple-Input Multiple-Output) 1 and WWAN MIMO2, which support 4×4 MIMO; the antennas connected to the WLAN card include two antenna structures, namely WLAN main set and WLAN diversity, which support 2×2 MIMO.

[0026] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.
[0027] An embodiment of the present utility model provides an antenna structure, which includes multiple wireless network cards, a switching switch unit, and a shared antenna unit; in an electronic product, there are multiple wireless communication methods, and correspondingly, wireless network cards that can meet the needs of wireless communication need to be configured. The wireless network cards are configured with a shared antenna unit, and the connected wireless network cards are switched through the switching switch unit. By setting the shared antenna unit, the number of antenna units can be reduced.
[0028] The following will describe in detail the structures, the positional relationships and the connection relationships of the structures in the antenna structure provided by the embodiments of the present utility model in conjunction with the accompanying drawings.
[0029] As Figure 1 and Figure 2 shown, in the embodiments of the present utility model, the wireless network card 10 includes a first wireless network card 11 and a second wireless network card 12. The first wireless network card 11 is a wireless local area network card, and the second wireless network card 12 is a wireless wide area network card. The fixed end of the switching switch unit 20 is connected to the shared antenna unit 30, and multiple switching ends of the switching switch unit 20 are respectively connected to the first wireless network card 11 and the second wireless network card 12; the switching switch unit 20 is used to connect the fixed end to the first wireless network card 11 and / or the second wireless network card 12.
[0030] The switching switch unit 20 includes a first switching switch unit 21 and a second switching switch unit 22. For example, the first switching switch unit 21 and the second switching switch unit 22 are single-pole double-throw switch units; the single-pole double-throw switch unit includes a fixed end and two switching ends. As shown in the figure, the fixed end of the single-pole double-throw switch unit is port 1, and the two switching ends are port 2 and port 3 respectively.
[0031] The shared antenna unit 30 includes a first shared antenna unit 31 and a second shared antenna unit 32. The first shared antenna unit 31 and the second shared antenna unit 32 can be connected to the first wireless network card 11 or the second wireless network card 12, so as to achieve the purpose of sharing.
[0032] Specifically, the port 1 of the first switching switch unit 21 is connected to the first shared antenna unit 31, the port 2 is connected to the first antenna interface 111 (antenna diversity interface) of the first wireless network card 11, and the port 3 is connected to the third antenna interface 121 (multiple input multiple output antenna interface) of the second wireless network card 12; the port 1 of the second switching switch unit 22 is connected to the second shared antenna unit 32, the port 2 is connected to the second antenna interface 112 (antenna main set interface) of the first wireless network card 11, and the port 3 is connected to the fourth antenna interface 122 (multiple input multiple output antenna interface) of the second wireless network card 12.
[0033] In the embodiments of the present utility model, the antenna structure further includes a dedicated antenna unit 40; the dedicated antenna unit 40 is not shared. The antenna interfaces of the first wireless network card 11 and / or the second wireless network card 12 are connected to the dedicated antenna unit 40. As shown in the figure, the second wireless network card 12 further includes a fifth antenna interface 123 and a sixth antenna interface 124, and the fifth antenna interface 123 (antenna main set interface) and the fifth antenna interface 123 (antenna diversity interface) are respectively connected to the dedicated antenna unit 40.
[0034] In the embodiments of the present utility model, the switching operations of the first switching switch unit 21 and the second switching switch unit 22 mainly include three situations, namely, the first wireless network card 11 operates, the second wireless network card 12 operates, or the first wireless network card 11 and the second wireless network card 12 operate simultaneously. The following will describe the above three situations with reference to the accompanying drawings.
[0035] When the first wireless network card 11 operates alone, the first switching switch unit 21 and the second switching switch unit 22 are respectively connected to port 2, so that the first common antenna unit 31 and the second common antenna unit 32 are connected to the first wireless network card 11, and the first wireless network card 11 supports 2 antennas.
[0036] When the second wireless network card 12 operates alone, the first switching switch unit 21 and the second switching switch unit 22 are respectively connected to port 3, so that the first common antenna unit 31 and the second common antenna unit 32 are connected to the second wireless network card 12. At the same time, the two independent antenna units 40 are connected to the second wireless network card 12, and the second wireless network card 12 supports 4 antennas.
[0037] When the first wireless network card 11 and the second wireless network card 12 operate simultaneously, the first switching switch unit 21 and the second switching switch unit 22 are respectively connected to port 2, so that the first common antenna unit 31 and the second common antenna unit 32 are connected to the first wireless network card 11. At the same time, the two independent antenna units 40 are connected to the second wireless network card 12. In this operating state, the first wireless network card 11 supports 2 antennas, and the second wireless network card 12 supports 2 antennas.
[0038] It can be seen from this that by setting the first common antenna unit 31 and the second common antenna unit 32, these two common antenna units 30 can be shared on the first wireless network card 11 and the second wireless network card 12. Therefore, when using the antenna structure, the number of antenna units can be reduced by 2.
[0039] Regarding the method of how to confirm the operating states of the first wireless network card 11 and the second wireless network card 12, taking a notebook computer as an example, the first wireless network card 11 is a Wi-Fi network, and the second wireless network card 12 is a 4G cellular network. When setting up the notebook computer, one can choose: always use the Wi-Fi signal, or always use the 4G cellular network, or switch to the 4G cellular network when the Wi-Fi signal is weak. When the user completes the corresponding selection, the processor sends a switching signal to the switching switch unit 20.
[0040] In the normal state (such as the initial state after each reboot), the switching switch unit 20 is connected to the position of port 2. In this state, the first wireless network card 11 and the second wireless network card 12 can receive Wi-Fi signals and 4G cellular network signals simultaneously. When the received signal is only a Wi-Fi signal, the processor sends a signal to the switching switch unit 20 to maintain the current state, that is, the state where the first wireless network card 11 operates alone. When the received signal includes both a Wi-Fi signal and a 4G cellular network signal, the current state is also maintained, that is, the state where the first wireless network card 11 and the second wireless network card 12 operate simultaneously.
[0041] When the received signal is only a 4G cellular network signal, the processor sends a switching signal to the switching switch unit 20, and the switching switch unit 20 is connected to the position of port 3.
[0042] The embodiment of the present utility model also provides an electronic product, including the above antenna structure. For example, the electronic product is a notebook computer, which includes a display end and a system end; the wireless network card 10 and the switching switch unit 20 are arranged on the main board of the system end, and the shared antenna unit 30 is arranged in the housing of the display end and / or the system end.
[0043] In the antenna structure, various wireless communication forms can be realized. Among them, in the form of using the shared antenna unit 30, the shared antenna unit 30 can be connected to multiple wireless network cards 10 for use, without separately configuring an antenna unit for each wireless network card 10, which can save the number of antenna units used.
[0044] In the embodiment of the present utility model, the switching form of the antenna structure is not limited to this.
[0045] For example, as Figure 3 and Figure 4 shown, the first wireless network card 11 and the second wireless network card 12 are respectively connected to the first shared antenna unit 31 and the second shared antenna unit 32. Through the switching of the first shared antenna unit 31 and the second shared antenna unit 32, the operation of the first wireless network card 11 or the operation of the second wireless network card 12 is realized.
[0046] In the technical solution of the present utility model, the antenna structure is integrally designed, which improves the development efficiency and shortens the design cycle; moreover, the number of antenna units is reduced, which can reduce the space occupied by the antenna structure, especially suitable for use in ultra-thin electronic products. In addition, the switching switch unit 20 has a lower cost compared to the antenna unit, so the cost of the antenna structure can be lower. Additionally, when designing multiple antennas for reference, the purpose of cost reduction and efficiency improvement can be achieved through the integrated design of shared antennas.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
