Embodiment Construction

[0032] figure 1 It is an application scene diagram of an antenna assembly provided in the embodiment of this application. Such as figure 1 As shown in , the scenario includes a controller 101 , an access point (access point, AP) 102 and multiple terminals 103 .

[0033] Wherein, the controller 101 can be used for centralized management and configuration of multiple APs 102, and forwarding of user data. The AP is used to provide wireless access services for multiple connected terminals 103 .

[0034] In high-density deployment scenarios, APs are generally installed at a height of 3-5 meters (m), and the radius of the covered cell can reach 5-8m. In this scenario, the number of users per unit area is usually large. Therefore, in order to ensure communication capacity, an omnidirectional antenna with a large angle can be used in the AP for signal coverage. However, since the number of channels is limited, the distance between APs working on the same frequency is generally sma...

Abstract

The invention discloses an antenna assembly and a wireless device, and belongs to the technical field of communication. The antenna assembly comprises N oscillators, a feed network and a printed circuit board (PCB), and N is an integer greater than or equal to 4, wherein the N oscillators and the feed network are all located on the PCB. The N oscillators are all connected with the feed network, each oscillator is provided with a radial part, the radial part of each oscillator points to the phase center of the antenna, and the length of the radial part of each oscillator is larger than the sumof the lengths of other non-radial parts. Thus, the main radiation direction of each oscillator is consistent with the direction of the radial part, each oscillator is equivalent to a line source, thebeam width is relatively narrow, and the sidelobe shift inhibition capability is enhanced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna component and a wireless device. Background technique [0002] A wireless access point (access point, AP) may use an omnidirectional antenna to provide large signal coverage, thereby satisfying a communication capacity requirement. However, when the distance between wireless APs working on the same frequency is small, the signals of adjacent wireless APs working on the same frequency will interfere with each other, thereby degrading the communication quality. The sidelobe suppression capability of the omnidirectional antenna determines the interference suppression capability of the entire network. [0003] Omnidirectional antennas mainly include dipole antennas, monopole antennas, and slot antennas. Take the dipole antenna as an example, the dipole antenna usually approximates a point source, has a wide beam width and weak sidelobe suppression ab...
