Abstract

A portable communication device comprises an antenna arrangement having a radiating antenna element and a grounding layer comprising an AMC material structure facing the radiating antenna element. The AMC material structure includes at least one layer of patches connected to a smooth conducting layer using conducting vias and electrical connection elements that selectively interconnect patches in a layer with other elements of the AMC structure. In this way a low profile antenna arrangement is provided that allows the coverage of a broad frequency band and/or directivity.
