Intelligent cabinet with RF shield

Abstract

An intelligent cabinet (1) comprises a housing (2) with an internal cavity (2a) and a separate compartment (2b). At least one RFID reader antenna (32) is arranged within the internal cavity (2a), and a cooling and/or ventilation arrangement (4) is arranged in the separate compartment (2b), outside the internal cavity (2a). At least one passage (5) is provided to allow air to circulate between the internal cavity (2a) and the cooling and/or ventilation arrangement (4). The internal cavity (2a) and the compartment (2b) are separated by an internal wall (6) within the housing (2), wherein the passage (5) comprises a plurality of openings (7a, 7b) through the internal wall (6). The openings are arranged directly in the internal wall (6) or in a separate part (8a, 8b) being connected to the internal wall. Each of the openings (7a, 7b) have a maximal extension in the range of 1-20 mm, and preferably 5-15 mm, and at least the surface of the internal wall (6) and/or the separate part (8a, 8b) comprises a conductive material. Hereby, the openings allow a flow of air through the openings, and at the same time provides attenuation or blocking of RF signals.
