APPARATUS FOR WIRELESSLY TRANSMITTING INFORMATION, COMMUNICATION TERMINAL FOR WIRELESSLY TRANSMITTING INFORMATION AND IMPEDANCE MATCHING METHOD

摘要

An apparatus for wirelessly transmitting information includes a transmitting/receiving unit and an antenna unit An electrical signal path is between the transmitting/receiving unit and the antenna unit. A front-end module contains at least one duplexer and is electrically connected into the signal path between the transmitting/receiving unit and the antenna unit. A detector unit is used for detecting signals proportional to radio-frequency signals propagating in the signal path. The detector unit is electrically coupled to the signal path between the transmitting/receiving unit and the front-end module.
