Title:
モバイル電話機用のアンテナダイバシティシステム
Document Type and Number:
Japanese Patent JP2006524022
Kind Code:
A
Abstract:
A system and method are provided for diversifying radiated electromagnetic communications in a wireless communication device having a plurality of embedded antennas. The method comprises sensing conducted electromagnetic transmission line signals communicated by the antennas, selecting between the antennas in response to sensing the transmission line signals, and modifying antenna electrical performance characteristics in response to sensing the transmission line signals. In some aspects sensing transmission line signals includes sensing transmission line signal power levels. For example, the power levels of the radiated signals conducted on the transmission lines can be sensed or the transmission line signal power levels of transmitted signals reflected by the antennas are sensed.
