Abstract

The invention relates to an aerial arrangement, especially for communications terminals. The need for compact construction of the communications terminals makes it difficult to integrate aerials into their casings. The aerial arrangement of the invention is notably shorter than prior art aerials and can thus be particularly easily integrated. This is achieved by the approximately zig-zag folding of the long section of an "inverted F aerial".
