Concepts for future multistandard and ultra wideband mobile terminal antennas using multilayer LTCC technology
Some key aspects of two different concepts of configurable antennas for future mobile terminal have been addressed in this paper. It has been shown that a coupling element in combination with a configurable tuning circuit can be used to excite the chassis of the mobile terminal to act as the entire antenna in many different frequency bands. However, when both the coupling element and the tuneable circuit elements are combined in a compact LTCC antenna component the achievable antenna efficiency is quite weak.
