Patent number: 7433720Abstract: A portable wireless terminal with a main body having a main board, and a battery pack detachably mounted in the main body and used as power supply means for the terminal, wherein the battery pack includes an upper case frame; a lower case frame coupled with the upper case frame to provide a predetermined installation space therebetween; a battery cell having a conductive outer surface fixed on the installation space; and a radiator fixed to an inner surface of the upper case frame, and having a feed pin and a ground pin that are exposed on the lower case frame along a detour route around the battery cell. Since the radiator is not installed inside the main body but inside the battery pack, an antenna mounting space can be removed from the main body, which contributes to a slim profile and a lightweight feature of the wireless terminal.Type: GrantFiled: November 21, 2005Date of Patent: October 7, 2008Assignee: Samsung Electronics Co., LtdInventor: Dong-Beom Seol

Patent number: 7298337Abstract: Disclosed herein is an antenna device for a mobile phone having a body housing, a sliding housing for sliding up or down lengthwise along the body housing, a sliding module for connecting the sliding housing to the body housing in the manner that allows the sliding housing to slide up or down, and a main antenna device in the sliding housing. In the antenna device for the mobile phone, at least one sub-antenna device is installed lengthwise facing the sliding module and is electrically connected to or separated from the body housing, slidingly approaching or moving away from the body housing along with the sliding module, and at least one connection unit electrically connects the sub-antenna device to the body housing for signal transmission between the sub-antenna device and the body housing.Type: GrantFiled: December 7, 2005Date of Patent: November 20, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Dong-Beom Seol, Jang-Hyun Nam

Patent number: 7233293Abstract: Disclosed herein is an antenna device for use with a portable wireless terminal having a main body, and a sub-body slidably coupled thereto, with a first antenna mounted in the main body and a second antenna mounted on the sub-body. The second antenna is selectively exposed to the outside as the sub-body moves slidingly on the main body. Conventional sliding-type terminals incorporate an antenna device in its main body that is interfered with by user body parts, thereby causing deteriorated performance. The antenna device of the present invention improves performance by using an additional second antenna mounted on the sub-body of the terminal to improve transmitting/receiving signal quality of the terminal. Furthermore, as such an antenna device is incorporated inside a sliding-type terminal or a pop-up type terminal, it is possible to eliminate risk of damage and to diversify the design of the terminal.Type: GrantFiled: July 15, 2005Date of Patent: June 19, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Wan-Sang Ryu, Jang-Hyun Nam, In-Taek Lee, Dong-Beom Seol

Publication number: 20060202895Abstract: An antenna device for a pop-up type wireless portable terminal is provided. The wireless portable terminal includes a main body. A pop-up body is provided to slide lengthwise on the main body so that the main body is partially opened or closed. A plate-type antenna radiator is provided at an appropriate position of an inner surface of the pop-up body. A whip antenna radiator is provided lengthwise across the main body and the pop-up body, for selectively contacting the main board of the main body and/or the plate-type antenna radiator along with opening and closing of the pop-up body.Type: ApplicationFiled: February 23, 2006Publication date: September 14, 2006Applicant: SAMSUNG ELECTRONICS., LTD.Inventors: Jang-Hyun Nam, Dong-Beom Seol

Publication number: 20060160487Abstract: Disclosed is a Near Field Communication (NFC) device that is attachable to a portable wireless terminal as an accessory. In the attachable NFC device, a locking unit is connected with a string to a portable wireless terminal for being jointly carried with the portable wireless terminal and an NFC module is detachably attached to the locking unit. The NFC module is detached from the locking unit and inserted to an external connector portion of the portable wireless terminal for near field communication with other device. The NFC device of the present invention can be jointly carried with the portable wireless terminal as an accessory, thereby preventing the loss of the NFC device. Also, the NFC module is designed as an external device that when it is used is capable of making an electrical connection with the portable wireless terminal, thereby increasing the security and decreasing the size of the portable wireless terminal.Type: ApplicationFiled: December 6, 2005Publication date: July 20, 2006Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jang-Hyun Nam, Dong-Beom Seol
