Patent number: 8892058Abstract: A communication system including a first station having at least two first narrow beam antennas and a second station having at least two second narrow beam antennas. The first and second stations establish a first communication path for wireless communication via a pair of first and second narrow beam antennas. When communication via the first communication path is disturbed by obstacles, the first and second stations automatically establish at least one alternative communication path, which is spatially different from the first communication path, for wireless communication using the at least two first narrow beam antennas and the at least two second narrow beam antennas.Type: GrantFiled: October 18, 2012Date of Patent: November 18, 2014Assignee: Sony Deutschland GmbHInventors: Masahiro Uno, Zhaocheng Wang, Volker Wullich, Kao-Cheng Huang

Patent number: 8253629Abstract: A rod antenna and a method for operating the rod antenna. The rod antenna includes a two-dimensional patch for radiating and/or receiving an electromagnetic wave, the patch extending along a plane defined by two coordinate axes orthogonal to each other. A feeding line is coupled to the patch for transferring signal energy to and/or from the patch, and a dielectric rod radiates and/or receives the electromagnetic wave, the rod extending longitudinally from the patch in direction of a third coordinate axis outside of the plane defined by the first two coordinate axes. A metal holder is coupled to the patch and to the rod for transferring the electromagnetic wave between the patch and the rod.Type: GrantFiled: December 19, 2005Date of Patent: August 28, 2012Assignee: Sony Deutschland GmbHInventors: Kao-Cheng Huang, Zhaocheng Wang, Vladimir Nikolajevic

Patent number: 7546038Abstract: The invention relates to a wireless optical data transmission system and a method for wireless optical transmission of data. The system comprises a data stream generator for generating at least two parallel data streams (18.1, 18.2, 18.3). The parallel data streams are transmitted by a number of separate optical transmitting devices (8, 9, 10) separately by emitting first optical signals. The system further comprises a corresponding number of detectors (19, 20, 21) for detecting the first optical signals and converting them into respective second signals (26.1, 26.2, 26.3) and an error correction unit (31) for correcting the amended second signals. Within a predistortion (29) unit each second signal (26.1, 26.2, 26.3) is amended individually with respect to a transmission channel used.Type: GrantFiled: January 26, 2006Date of Patent: June 9, 2009Assignee: Sony Deutschland GmbHInventors: Zhaocheng Wang, Kao-Cheng Huang, Masahiro Uno

Patent number: 7212163Abstract: A circular polarized array antenna includes: groups of at least one set of patches for radiating and/or receiving a circular polarised electromagnetic wave; and a network of feeding lines, each feeding line being coupled to and extending longitudinally or vertically to one of the sets for transferring signal energy to and/or from the set. Each of the feeding lines coupled to the sets is pointing into a direction different from the pointing direction of the other feeding lines in order to achieve a circular orientation of the network of feeding lines.Type: GrantFiled: February 9, 2005Date of Patent: May 1, 2007Assignee: Sony Deutschland GmbHInventors: Kao-Cheng Huang, Stefan Koch, Masahiro Uno

Publication number: 20060116092Abstract: The present patent application is directed to a communication system 0 comprising a first station 1 with a first narrow beam antenna 31 and a second station 2 comprising a second narrow beam antenna 41, wherein the first and second stations 1, 2 are adapted to establish a first communication path 7a for wireless communication via said first and second narrow beam antennas 31, 41, respectively. It is a disadvantage with such a communication system that communication via said first communication path might be disturbed by randomly appearing obstacles. In consequence, the data transmission rate is reduced. According to the present invention said first and second stations 1, 2 are adapted to automatically establish at least one alternative communication path 7b, 7c for wireless communication via said first and second narrow beam antennas 31, 41, said alternative communication path 7b, 7c being spatially different from said first communication path 7a.Type: ApplicationFiled: November 17, 2005Publication date: June 1, 2006Inventors: Masahiro Uno, Zhaocheng Wang, Volker Wullich, Kao-Cheng Huang
