Abstract

A field device for automation technology, wherein the field device has a metal housing for accommodating a field device electronics, an RFID chip and a first RFID antenna for wireless communication and/or energy transmission between an RFID reading device arranged outside of the field device. The first RFID antenna is spaced from a neighboring wall of the metal housing, wherein shielding is provided between the first RFID antenna and the neighboring wall of the metal housing. The separation between the first RFID antenna and the wall of the metal housing and the shielding between the first RFID antenna and the neighboring wall of the metal housing are so dimensioned, that the metal housing does not prevent wireless communication and/or energy transmission between the RFID reading device and the field device.
