20120075160 | ANTENNA MODULE - An antenna module includes an antenna, a tunable matching circuit, a power detector and a control unit. The antenna comprises a feeding point. The tunable matching circuit, electrically connected between the antenna and the power detector and configured to provide a loading impedance, comprises a plurality of tunable impedance elements connected to each other and electrically connected to the feeding point as well. The power detector is electrically connected between the tunable matching circuit and a power amplifier and configured to detect a power indicator. The control unit, electrically connected to the tunable matching circuit and the power detector, is configured to read the power indicator and RSSI to generate a control signal for the tunable matching circuit, which consistently changes the loading impedance to achieve impedance matching. | 03-29-2012 |
20120172084 | MOBILE COMMUNICATION DEVICE AND METHOD FOR TRANSCEIVING DATA AND VOICE THEREOF - A mobile communication device and a method for transceiving data and voice thereof are proposed. The mobile communication device includes a receiver, a first antenna module, and a second antenna module. The receiver is used to output voice. The first antenna module is disposed in the mobile communication device at a first side close to the receiver, and is used to transceive data of a first wireless communication system or a second wireless communication system. The second antenna module is disposed at a second side opposite to the first side, and is used to transceive voice of the first wireless communication system. A first distance between the first antenna module and the receiver is less than a second distance between the second antenna module and the receiver. | 07-05-2012 |
