ABSTRACT:
The invention relates to a dual-band antenna for preferable operation in the GSM and DCS frequency range. The dual-band antenna at the same time has the functionality of a diplexer. This makes it possible to produce wireless communication devices with one component less, which in turn reduces weight and production cost.
