Patent number: 9093753Abstract: An artificial magnetic conductor includes a conductor layer, a ground layer, and a via. The conductor layer is formed in a first direction and includes a plurality of grid cells. The ground layer is formed in a second direction that is opposite to the first direction and generates a lower frequency than that of an artificial magnetic conductor including a plurality of grid cells having the same size as that of the plurality of grid cells of the conductor layer and a conductor plate having a form that is not modified. The via is formed between the conductor layer and the ground layer to electrically connect the conductor layer and the ground layer.Type: GrantFiled: December 23, 2010Date of Patent: July 28, 2015Assignee: INDUSTRY-ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITYInventors: Young Bae Jung, Soon Young Eom, Soon Ik Jeon, Young Joong Yoon, Jihwan Ahn, Ji Hwan Yoon

Patent number: 7683846Abstract: An ultra wide band receiver system comprising a ultra wide band antenna and an active circuit. The ultra wide band antenna including a power feed operable to receive electromagnetic energy. The ultra wide band antenna further includes a radiator operable to be excited by the electromagnetic energy fed through the power feed to radiate an electromagnetic wave. The radiator has a metal layer. The active circuit includes a pair of parallel coupled lines arranged on a first side of the radiator. The pair of parallel coupled lines is operable to block DC current. The active circuit further includes at least one defected ground structure formed on a second side of the radiator. The defected ground structure is formed on an etched out part of the metal layer.Type: GrantFiled: June 30, 2006Date of Patent: March 23, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Ick-Jae Yoon, SeongSoo Lee, Young Joong Yoon, Young-Hwan Kim, Young-Eil Kim, Hyungrak Kim

Patent number: 7557755Abstract: An ultra wideband antenna is provided that filters a predetermined frequency signal. The ultra wideband antenna includes a power feeding part that receives a supply of an external electromagnetic energy; a radiator excited by the electromagnetic energy fed through the power feeding part and radiating an electromagnetic wave; and a stub, provided on the radiator in a direction parallel to a direction of an electric field formed by the electromagnetic wave, that intercepts transmission/reception of a predetermined frequency band signal. The length of the stub may be ¼ of a wavelength of the intermediate frequency of the predetermined frequency band to be removed to filter the corresponding frequency band signal. The ultra wideband antenna simplifies the construction of an ultra wideband receiving system with the power loss and noise characteristics of the system improved.Type: GrantFiled: March 2, 2006Date of Patent: July 7, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-min Han, Young-hwan Kim, Seong-soo Lee, Hyung-kuk Yoon, Young-joong Yoon, Yo-han Lim, Ick-jae Yoon, Hyung-rak Kim

Patent number: 7522106Abstract: An antenna having an extended operation frequency bandwidth that includes: a feed, and a plurality of radiators which are connected to the feed to receive current and divided at the feed. Accordingly, the RFID radio signals and the mobile communication radio signals can be transmitted and received via the single antenna because the frequency bandwidth is expanded. Therefore, the efficiency of the antenna can be improved and the mobile communication terminal can be miniaturized. Furthermore, since the antenna obtains the increased gain, the communication quality of the antenna can be enhanced and the power consumption can be reduced.Type: GrantFiled: November 8, 2006Date of Patent: April 21, 2009Assignees: Samsung Electronics Co., Ltd., Industry-Academic Cooperation Foundation, Yonsei UniversityInventors: Yohan Lim, Kihun Chang, Young Joong Yoon, Ick-Jae Yoon, Young-Eil Kim, Yongjin Kim

Patent number: 7504913Abstract: A DC block with a band-notch characteristic using a defected ground structure (DGS), includes a pair of coupled lines for being formed parallel to each other on one surface of a dielectric and blocking a flow of a DC, and at least one DGS for being formed on an area of the rear surface of the dielectric corresponding to each coupled line and comprising an etched region formed by etching a part of a ground surface bonded to the dielectric and a metal region formed in the etched region. Accordingly, the stop band of the desired bandwidth in the desired communications band can be formed and the size of the communications system can be reduced.Type: GrantFiled: June 30, 2006Date of Patent: March 17, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Ick-Jae Yoon, SeongSoo Lee, Young Joong Yoon, Young-Hwan Kim, Young-Eil Kim, Hyungrak Kim
