Abstract
A filter element () for filtering fluids, such as hydraulic fluids or gases, is in a filter housing () having an inlet () for the fluid to be filtered, an outlet () for the filtered fluid. The filter element has a data storage (). Data stored in the data storage () is electronically readable from the data storage () by a read and/or write device (). An antenna () extends outside the data storage () and provides the signal coupling between the data storage () and the read and/or write device (). The antenna () extends at least in sections about a longitudinal axis () of the filter element () such that independently from the angular position of the filter element () and the attached data storage () a signal coupling between the data storage () and the read and/or write device () is ensured.
