摘要:
An apparatus and method for automatically matching a frequency of an antenna in a wireless terminal are provided. The apparatus includes a duplexer for classifying frequencies transmitted/received through the antenna of the wireless terminal, transmitting the reception frequency received in the antenna to an automatic matching module, and transmitting a transmission frequency, which is received from the automatic matching module, to the antenna; the automatic matching module for automatically matching impedance for the reception frequency received from the duplexer, transmitting the impedance-matched reception frequency to an amplifier, automatically matching impedance for the transmission frequency received from the amplifier, and transmitting the impedance-matched transmission frequency to the duplexer; and a controller for controlling the automatic matching module to automatically match the impedance for the transmission/reception frequencies.

An apparatus and method for automatically matching an impedance for a frequency of an antenna in a wireless terminal. The apparatus automatically matches an impedance for a frequency of an antenna in a wireless terminal. The apparatus includes a duplexer for classifying frequencies transmitted/received through the antenna of the wireless terminal, an automatic matching module for transmitting the reception frequency, which is received from the duplexer, to an amplifier after automatically matching impedance for the reception frequency and for transmitting the transmission frequency, which is received from the amplifier, to the duplexer after automatically matching impedance for the transmission frequency, and a controller for controlling the automatic matching module to automatically match impedance for the transmission/reception frequency.
摘要:
Provided is an antenna apparatus for a portable terminal including a first antenna pattern, and a second antenna pattern formed to correspond to the first antenna pattern, so that the second antenna provides a capacitive coupling along with the first pattern, thereby configuring a divergent type antenna with the second antenna pattern. The antenna apparatus configured in this manner comprises a pair of meander line antennas, whereby the antenna apparatus can efficiently suppress the generation of noise while being easily housed within the terminal. Furthermore, the antenna apparatus has an advantage of easily enhancing a specific absorption ratio (SAR) induced in a human body, which is an important factor for defining the function and quality of an antenna apparatus.

An antenna device for a portable terminal, a portable terminal, and a method for providing an antenna device in a portable terminal are provided. The antenna device includes a radio frequency (RF) board on the portable terminal, an antenna connected to the RF board, a connection line for connecting the RF board to the antenna device, and matching circuits at both ends of the connection line. The matching circuits compensate for loss from the connection line itself and connection losses so that a signal can be adjusted in accordance with the properties of the antenna. Consequently, the properties of the antenna device are stabilized.

An apparatus and method for controlling a portable home theater (PHT) with multiple functions using a wireless terminal are provided. When the PHT is selected in the wireless terminal, a determination is made as to whether the PHT is connected. When the PHT is connected, an operating mode is switched to a PHT control mode. In the PHT control mode, a function provided in the PHT is selected. The wireless terminal then controls the selected function provided in the PHT.
