Abstract: A consumption meter for measuring consumption data of a supplied utility is provided, the consumption meter comprising: a housing with an opening, where the housing forms a closed compartment when the opening of the housing is closed with a cover; a communication module provided in the closed compartment; a front plate provided in the closed department and arranged adjacent to the cover, wherein the front plate has a first front plate surface facing the cover, and a second front plate surface facing opposite; and an antenna comprising an antenna body with an antenna conductive element, which is connected to the communication module; wherein the front plate has an indentation arranged between the first and the second front plate surfaces, and wherein the antenna body is arranged in the indentation. The consumption meter provides an antenna with a high transmission performance. Further, the antenna is mechanically supported, and is arranged inside the closed compartment, eliminating the need of any feedthrough across the housing wall.
