Abstract
A method and apparatus for providing more reliable wireless communication and power to sensors in electrically challenging bioprocess environments is disclosed. An unconnected antenna is located within the bioprocess environment, preferably in the same plane as the primary powered antenna. This unconnected antenna, also referred to as reflective antenna, enhances and confines the electromagnetic field created by the powered antenna. This reflective antenna is incorporated in or proximate to the devices containing a sensor or communication device. In one embodiment, the reflective antenna is incorporated into the filter housing. In another embodiment, it is incorporated into the filtering element itself. In another embodiment, it is incorporated into or affixed on the disposable bioprocess components, such as bags and tubes.
