Publication number: 20140141729Abstract: A signal transceiver is provided. The signal transceiver comprises a body, a first wave guide, at least one first feed conductor, a second wave guide, at least one second feed conductor, and a path-modulating structure. The first wave guide is formed in the body and comprises a first end and a second end, wherein a first opening is formed on the first end. The first feed conductor is disposed in the first wave guide and located on the second end. The second wave guide is formed in the body and comprises a third end and a fourth end, wherein a second opening is formed on the third end. The second feed conductor is disposed in the second wave guide and located on the fourth end. The path-modulating structure is substantially located between the first wave guide and the second wave guide.Type: ApplicationFiled: July 16, 2013Publication date: May 22, 2014Inventors: I-Ching LAN, Chung-Min LAI, Chang-Hsiu HUANG

Publication number: 20120146866Abstract: A wireless communication antenna device includes a horn antenna and a waveguide. The horn antenna for transmitting or receiving a polarized wireless electromagnetic wave having a first electric field component and a second electric field component, the first electric field component and the second electric field component being orthogonal with each other. The waveguide connected to the horn antenna, for propagating the polarized wireless electromagnetic wave. Wherein a first opening of the waveguide includes a side corresponding to the first electric field component and another side corresponding to the second electric field component, and a length of the side corresponding to the first electric field component is different from a length of the side corresponding to the second electric field component, such that the first electric field component and the second electric field component have a phase difference therebetween when the polarized wireless electromagnetic wave is propagated in the waveguide.Type: ApplicationFiled: December 28, 2010Publication date: June 14, 2012Applicant: WISTRON NEWEB CORPORATIONInventors: Chang-Hsiu HUANG, Chung-Min LAI, I-Ching LAN
