Patent number: 10263328Abstract: The present disclosure provides a device for wireless access, which pertains to the technical field of wireless network. The device for wireless access includes a device body; a radio frequency circuit disposed inside the device body; and a plurality of antenna units disposed on an external surface of the device body, each of the plurality of antenna units being connected to the radio frequency circuit; wherein each of the plurality of antenna units comprises an antenna oscillator, and the antenna oscillators on each two adjacent antenna units of the plurality of antenna units are misaligned with each other. By disposing antenna oscillators of adjacent antenna units on the misaligned regions of the respective antenna unit, the interference of co-frequency signals between adjacent antenna units may be reduced, and the isolation of adjacent antenna units may be enhanced. Thus, adjacent antenna units may be disposed at a reduced distance therebetween.Type: GrantFiled: September 15, 2017Date of Patent: April 16, 2019Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.Inventors: Yanbing Lei, Jianquan Wang
