Patent number: 11387551Abstract: The present invention discloses a triple-resonant null frequency scanning antenna, which belongs to the technical fields of the Internet of Things and microwave. The triple-resonant null frequency scanning antenna comprises a circular sector magnetic dipole arranged on a medium substrate, and rectangular notches are symmetrically arranged on a sector patch of the circular sector magnetic dipole. The circular sector magnetic dipole is fixed on the medium substrate by a second shorting pin and third shorting pins, an flared angle of the circular sector magnetic dipole is a first central angle, and two third shorting pins are present and are symmetrically arranged on both sides of the angular bisector of the first central angle.Type: GrantFiled: June 16, 2020Date of Patent: July 12, 2022Assignee: NANJING UNIVERSITY OF POSTS AND TELECOMMUNICATIONSInventors: Wenjun Lv, Sijie Li, Yun Shao, Jianyuan Wang, Han Wu, Zhibin Zhao, Zhifang Wu, Xiaohui Li, Hongbo Zhu, Xiaofei Li

Patent number: 11349216Abstract: The present invention discloses a sector dual-resonant dipole antenna. Radiation elements of the antenna are two identical sector patches. Two identical rectangular notches can be symmetrically arranged or two identical tuning stubs can be symmetrically loaded on the sector patches at positions deviating from the central axis of the two sector patches. Exciting points are symmetrically arranged on sides of the sector patches close to a central axis. The present invention realizes a wide beamwidth radiation characteristic through a two-dimensional sectorial resonator, and then the notches are arranged or the tuning stubs are loaded at appropriate positions of two arms of the sectorial resonator, and thereby a dual-resonant characteristic can be realized within a working band.Type: GrantFiled: June 16, 2020Date of Patent: May 31, 2022Assignee: NANJING UNIVERSITY OF POSTS AND TELECOMMUNICATIONSInventors: Wenjun Lv, Zhibin Zhao, Zhuang Li, Han Wu, Sijie Li, Jianyuan Wang, Zhifang Wu, Xiaohui Li, Hongbo Zhu, Xiaofei Li

Patent number: 8576701Abstract: The present invention relates to the field of communication technologies and discloses a method, an apparatus, and a system for active-standby switchover. The method includes: copying at least one packet group to a standby board; recording the copied packet group and generating a transmission rule chain table of an active board according to a sequence of copying, so that the standby board generates a transmission rule chain table of the standby board which is the same as the active transmission rule chain according to the sequence of copying; and transmitting the packet group according to the sequence of the transmission rule chain table of the active board. By using the method, resuming transmission from a breakpoint upon an active-standby switchover is enabled.Type: GrantFiled: February 3, 2012Date of Patent: November 5, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Hui Ni, Li Liu, Zhibin Zhao, Changzhi Guo
