In this paper we present part of a long term research project that aims on designing a (re-)configurable multistandard antenna element for 4G (4th Generation) mobile terminals based on LTCC (Low Temperature Co-fired Ceramic) technology. The antenna itself is a coupling element that efficiently excites the chassis of the mobile terminal to radiate as an entire antenna. Coupling is optimized by a reactive tuning circuit. Several of these tuning circuits are realized in a single LTCC component and can be multiplexed to the antenna by a SPnT (Single Pole n Thru) antenna switch integrated into the LTCC component. The coils and capacitor in the LTCC component are configurable on the top-layer of the component. Thus, the component is configurable according to different mobile terminal chassis configurations and multiple bands.
