Patent number: 10915718Abstract: A radio frequency (RF) positioning system comprises transceivers, positioning tags, processing units and a computing host. One or multiple positioning tags are attached to a target object being located. When the transceivers first generate and transmit transmission signals, one or multiple tag antennas in the positioning tag receive the transmission signals and transmit back modulated signals. The transceivers then receive and transmit the modulated signals to the processing units. The processing units are configured to obtain received signals, and calculate frequency differences based on the received signals and the transmission signals. The computing host calculates position coordinates of tag antennas based on the frequency differences, and then calculates the orientation of the target object being located according to the position coordinates of the tag antennas.Type: GrantFiled: December 21, 2018Date of Patent: February 9, 2021Assignee: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTREInventors: Nai-Chun An, Yuan-Chih Lin, Hsiu-An Tsai, Shuo-Ching Chen, Chih-Lung Lin

Publication number: 20190165467Abstract: A multi-antenna system uses non-radiation coupling edges to achieve isolation. A first radiation antenna, a second radiation antenna and at least one isolator are disposed on the surface of a substrate, wherein each of the first radiation antenna and the second radiation has a resonance radiating portion, a feeding portion, and at least one non-radiation coupling edge. The isolator is disposed between the first and second radiating antennas, extending from the non-radiation coupling edge of the first radiating antenna to that of the second radiating antenna. By disposing the isolator beside the non-radiation coupling edges, the near field coupling energy between the first and second radiating antennas is cancelled out, thereby improving the isolation of the antenna. By changing the length of the isolator, the resonant frequency of the system can be adjusted.Type: ApplicationFiled: October 22, 2018Publication date: May 30, 2019Applicant: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTREInventors: Yuan-Chih LIN, Jheng-Hong SHIH, Zong-Yi YANG
