PROBLEM TO BE SOLVED: To disclose wireless communication that achieves higher reliability and a method and an apparatus which supply electric power to a sensor in an electrically difficult bio process environment.SOLUTION: In a bio process environment, a non connection antenna is preferably disposed on the same plane as a first powered antenna. The non connection antenna is also referred to as a reflection antenna and strengthens and limits an electromagnetic field generated by the powered antenna. The reflection antenna is incorporated into or located closed to an apparatus including a sensor or a communication device. According to a first embodiment, the reflection antenna is incorporated into a filter housing. In a second embodiment, the reflection antenna is incorporated into a filtering element itself. In a third embodiment, the reflection antenna is incorporated into or attached to a disposable bio process item such as a bag or a tube. |
