Antenna system and network switching method

Abstract

The invention discloses an antenna system and a network switching method. The antenna system comprises at least two antenna units, at least two network card units, a toggle switch and a control unit.Each antenna unit at least has a main antenna and an auxiliary antenna. The at least two network card units respectively correspond to the antenna units. The main antenna of each antenna unit is connected to the corresponding network card unit. The auxiliary antenna of each antenna unit is connected to the corresponding network card unit through the toggle switch. The control unit is connected with the toggle switch to control the on / off of signal connection between the auxiliary antenna of each antenna unit and the corresponding network card unit. Compared with the prior art, the antenna system and the network switching method of the invention have the advantage that the space needed to set up a feeder line repeatedly is reduced by improving the structure of the antenna system and connecting the lead-out feeders of all antennas to an embedded controller through one toggle switch for control.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna system and a network switching method. Background technique [0002] It is known that WLAN (Wireless Local Area Networks) refers to wireless local area networks. Compared with wired networks, it does not need to use physical cable components, but uses electromagnetic waves to communicate in the air, so that users can have More flexibility and mobility, it has been widely used in many known electronic smart devices. WWAN (Wireless Wide Area Network) refers to wireless wide area network, which enables electronic devices such as laptops and tablets to connect to the Internet within the coverage of cellular networks. [0003] At present, the above-mentioned WLAN, WWAN and other network connection functions are realized by using radio frequency antennas on notebooks or 3C electronic products with metal casings. It is known that the antenna has certain requirements...

Problems solved by technology

[0005] It is known that the signal sending and receiving frequency of wireless wide area network is generally between 699MHZ-2690MHZ, which belongs to the low frequency signal segment, while the signal sending and receiving frequency of wireless local area network generally has two bands of low frequency (1710MHZ-2690MHZ) and high frequency (5150MHZ-5850MHZ). Therefore, the signal sending and receiving frequencies of wireless local area network and wireless wide area network overlap to a certain extent. However, in current electronic products, because the antennas are set correspondingly, some antennas are actually redundant, and multiple sending and receiving antennas are set separately. It will also cause the size of the antenna to become larger and take up more space. Moreover, with the emergence of new 5G networks, more network signal antennas of different frequency bands will be placed in electronic products in the future, so if only through It is already difficult to make the antenna smaller by designing the structure of a single antenna itself, and setting up multiple transmitting and receiving antennas will still occupy a large space. The corresponding circuit is fed, and the structure is complex. When switching the network type, some antennas stop working completely, and the antenna utilization efficiency is very low, so we urgently need a new solution.
