Patent number: 8909166Abstract: An apparatus and method for controlling a multi-band antenna in a mobile communication terminal are provided. An apparatus for controlling a multi-band antenna in a mobile communication terminal includes a modem, an antenna unit, a Radio Frequency (RF) processing unit, and a switch module. The modem outputs at least one control signal corresponding to a target frequency band. The antenna unit changes a resonance frequency of the antenna according to the at least one control signal. The RF processing unit includes a plurality of transmission/reception (TX/RX) paths and processes TX/RX signals. The switch module connects the antenna to one of the TX/RX paths according to the at least one control signal.Type: GrantFiled: June 28, 2011Date of Patent: December 9, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-Ho Park, Sung-Hwan Ko, Suk-Chan Hong, Young-Hwan Jung

Patent number: 8884829Abstract: A wireless communication device includes a first antenna, a second antenna, a first light sensor adjacent to the first antenna, a second light sensor adjacent to the second antenna, a controller, and a magnetic member movably located between the first antenna and the second antenna. When one of the first and second antennas in a state of receiving/transmitting wireless signals is covered by a user's hand, the nearby light sensor sends a pulse signal to the controller. The controller receiving the pulse signal controls the first and second antennas to change their magnetic polarity, enabling the magnetic member to be separated from one of the first and second antennas and attached to the another one, thereby choosing one of the first and second antennas, or a combination of one of the two antennas and the magnetic member to receive/transmit the wireless signals.Type: GrantFiled: October 9, 2012Date of Patent: November 11, 2014Assignee: FIH (Hong Kong) LimitedInventors: Chuan-Chou Chi, Chih-Yang Tsai, Pai-Cheng Huang, Hao-Ying Chang
