Problems solved by technology

[0002] With the rapid development of wireless communication technology, the application range of wireless local area network (WLAN) is becoming wider and wider. From the perspective of spectrum resource allocation, the bandwidth and transmission rate in the original 802.1b / g (2.4-2.4835GHz) protocol are It is very limited and can no longer meet the requirements of today's data communication. Therefore, it is an inevitable trend of WLAN development to be compatible with the 802.1la (5.15-5.35GHz, 5.725-5.825GHz) protocol with higher frequency and more abundant spectrum resources. The WLAN antenna must meet the dual-frequency characteristics. In the field of wireless local area network (WLAN), in order to achieve all-round coverage of the signal, an omnidirectional antenna must be used, and in order to achieve a certain coverage, the antenna is required to have a higher gain. Therefore, the research and development High-gain omnidirectional antennas capable of dual-band work on wireless LANs are particularly important
[0003] The WIFI antenna in the prior art has many cables and complex routing. In order to reduce the mutual coupling between the cables and the antenna unit, it is necessary to increase the distance between the unit arm and the feeder cable, resulting in a large antenna
Moreover, it works in a single frequency band, and the loss is large, which does not meet the application requirements, or there is a problem of low gain, and the use effect is not good.

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0030] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should ...

Abstract

The invention is applicable to the technical field of wireless communication devices and discloses a dual-band omnidirectional WIFI (wireless fidelity) antenna. The dual-band omnidirectional WIFI antenna comprises a dielectric plate and two pairs of dual-band radiating elements, the dual-band radiating elements are connected to the dielectric plate, a balance microstrip line is connected between the two dual-band radiating elements, each dual-band radiating element comprises two low-frequency radiating arms and two high-frequency radiating arms, and the low-frequency radiating arms and the high-frequency radiating arms are symmetrically arranged on two sides of the balance microstrip line. The dual-band omnidirectional WIFI antenna is wide in a covered range and high in gain.
