Problems solved by technology

Obviously, for a router with a size of 100mm (length) x 100mm (width), the size of the existing dual-band WiFi antenna system supporting 2 antenna groups is too large. Therefore, it is necessary to carry out the above-mentioned antenna system in the router Further improvement, aiming to realize dual-band WiFi antenna system with more than 2 antenna groups without increasing the size of the antenna

Embodiment Construction

[0019] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0020] The most critical idea of ​​the present invention is: three antenna assemblies are arranged at the end of the PCB board of the router, and the second antenna assembly has the characteristics of self-isolation, which meets the requirements of isolation and gain flatness of the whole antenna; The bending part provided on the branch and the short antenna can reduce the headroom of the antenna, and is more suitable for small-sized routers.

[0021] Please refer to figure 1 and figure 2 , a dual-band WiFi antenna system for a wireless router, including a router housing, a PCB board is placed in the wireless router housing, and a first antenna assembly 2, a second antenna assembly 3 and a first antenna assembly 3 are fixed on the PCB board 1 Three antenna co...

Abstract

The invention discloses a dual-band WiFi antenna system for a wireless router, which includes a router housing, a PCB board is placed inside the wireless router housing, and a first antenna assembly, a second antenna assembly and a second antenna assembly are fixed on the PCB board. Three antenna components, the first antenna component, the second antenna component and the third antenna component are located at the same end of the PCB, and the second antenna component is located between the first antenna component and the third antenna component. The invention has better self-isolation characteristics, meets the requirements of isolation conditions between antennas and gain flatness, and provides bending parts on the long antennas of the antenna assembly, which can reduce the gap between the antennas and is suitable for small-sized routers.

Description

technical field [0001] The present invention relates to a WiFi antenna system, in particular to an antenna system for a wireless router capable of supporting dual-band WiFi. Background technique [0002] In the research of high-speed wireless data exchange between portable devices and routing equipment, the dual-band WiFi system of 2.4G frequency band and 5G frequency band is the key research object. Up to now, 2x2 dual-band WiFi antenna system has been widely used in routing equipment. The 2x2 dual-band WiFi antenna system means that two sets of antennas are set on the routing device, and two sets of antennas are set on the portable device. In the above structure, the design requirements of the dual-band WiFi antenna system set on the routing device are more stringent than those of the dual-band WiFi antenna system set on the portable device. This is because, in order to ensure that signals can be received wirelessly at any position on the horizontal plane or at any angle...
