The shield and the interconnect device, with components and antennas arranged on it, are surrounded by the housing. A medium is arranged between the shield and the housing, and this medium has a thermal conductivity greater than 0.15 W/(m·K). ## Claims ### Claim 1 A radar device comprising: a lower housing; a radome coupled to the lower housing; a shield connected to the lower housing; and an interconnect device connected between the shield and the radome and having an electronic circuit arrangement arranged on a first side proximate to the shield and antennas arranged on a second side proximate to the radome and opposite the first side, where the shield and the interconnect device are surrounded by the lower housing, and, with the electronic circuit arrangement and antennas arranged on the interconnect device, wherein the radome closes the shield and the interconnect device inside the lower housing, and wherein a medium that has a thermal conductivity greater than 0.15 W/(m·K) is arranged between the shield and the lower housing. ### Claim 2 (depends on 1) The radar device in accordance with claim 1, wherein the shield is connected to the housing through gluing, welding or the use of another firmly bonded connection. ### Claim 3 (depends on 2) The radar device in accordance with claim 2, wherein the medium is an adhesive and the adhesive creates a bond between the shield and the lower portion of the housing. ### Claim 4 (depends on 3) The radar device in accordance with claim 3, wherein the adhesive is a thermally conductive adhesive. ### Claim 5 (depends on 3) The radar device in accordance with claim 3, wherein the adhesive contains at least a thermally conductive filler material. ### Claim 6 (depends on 1) The radar device in accordance with claim 1, wherein the shield is in contact with both the lower portion of the housing and other components of the radar device through the medium. ### Claim 7 (depends on 1) The radar device in accordance with claim 1, wherein a part of the lower portion of the housing, which is in contact with the shield structure through the medium, is manufactured entirely or partially of plastic, where the plastic contains a material that has a thermal conductivity greater than a thermal conductivity of other materials contained in the plastic. ### Claim 8 (depends on 1) The radar device in accordance with claim 1, wherein the housing features cooling fins. ### Claim 9 (depends on 1) The radar device in accordance with claim 1, wherein the shield is a plastic part with embedded metal particles having a thermal conductivity greater than the plastic has. ### Claim 10 (depends on 1) The radar device in accordance with claim 1, wherein the housing or a part of the housing and the shield structure are a single piece. ### Claim 11 (depends on 10) The radar device in accordance with claim 10, wherein the single piece is a plastic part with external metalization, with a metal core and/or with embedded particles, such as metal particles, with a thermal conductivity greater than the plastic. ### Claim 12 (depends on 1) The radar device in accordance with claim 1, wherein the shield has at least one hole into or through which at least one component of the electronic circuit arrangement protrudes, while remaining components of the electronic circuit arrangement, with the exception of connecting elements, are arranged entirely between the first side of the interconnect device and the shield. ### Claim 13 (depends on 12) The radar device in accordance with claim 12, wherein the at least one component has a housing made of metal or at least partially made of metal. ### Claim 14 (depends on 13) The radar device in accordance with claim 13, wherein there is an electrically conducting connection between the metal of the housing of the at least one component and the shield. ### Claim 15 (depends on 13) The radar device in accordance with claim 13, wherein there is an electrically conducting connection in the form of a ground potential between the metal of the housing of the at least one component and the shield.
