A filter arrangement having three or more stacked metallization layers separated by printed circuit board, PCB, layers. Each metallization layer includes an aperture. The filter arrangement has a plurality of via-holes extending though the stacked metallization layers and through the separating Dielectric material layers, whereby the via-holes and the metallization layers delimit a cavity in each Dielectric material layer. The cavities in two consecutive Dielectric material layers being coupled by the aperture in the single metallization layer separating the two consecutive Dielectric material layers. The aperture of a topmost metallization layer being arranged as antenna element. The filter arrangement having a signal interface arranged as a conduit connecting at least one dielectric material layer to an exterior of the filter arrangement.
