Patent number: 8896486Abstract: A multiband antenna comprises a feeder member, a radiation conductor, a short-circuit member, a grounding plane and a feeder cable. The feeder member has a first coupling side. Two end of the short-circuit member are respectively connected with the radiation conductor and the grounding plane. The short-circuit member has a second coupling side parallel to and conformable to the first coupling side with a gap existing therebetween. The feeder cable has a central wire and an outer wire respectively connected with the feeder member and the grounding plane. The feeder member transmits a high-frequency fed-in signal to the short-circuit member in a capacitive coupling way. The multiband antenna of the present invention has a simplified antenna structure, a miniaturized size and wide frequency bands.Type: GrantFiled: July 12, 2013Date of Patent: November 25, 2014Assignee: Advanced-Connectek Inc.Inventors: Tsung-Wen Chiu, Fu-Ren Hsiao, Po-Yuan Liao

Publication number: 20080227408Abstract: An apparatus and a method for switching a frequency band of an antenna, used in an electronic device having an antenna are provided. The apparatus comprises a driving device, a switching device, and a radio frequency module. The switching device is used for adjusting the frequency band of the antenna to cover a system frequency band of a communication system adopted by the electronic device. The driving device is used for receiving a switching command from the electronic device and driving the switching device accordingly, in which the switching command indicates the communication system adopted by the electronic device. The radio frequency module is used for performing down frequency conversion on the signals output by the switching device and performing up frequency conversion on the signals to be input to the switching device. Accordingly, more than two frequency bands can be supported by the electronic device with a single antenna.Type: ApplicationFiled: March 17, 2008Publication date: September 18, 2008Applicant: ADVANCED CONNECTEK INC.Inventors: Chih-Ren Hsiao, Po-Yuan Liao, Tsung-Wen Chiu, Fu-Ren Hsiao
