In this overview paper we have studied different options for implementing antennas in multi-system mobile terminals that are becoming more and more common. The presented recent results included broadband antenna elements with multi-frequency matching circuits and the use of tunable or selectable centre frequency. All the solutions are based on the idea of shifting complexity from the 3D antenna element structure to RF circuit structures. Due to the ongoing development or new improved RF technologies and components that enable adaptivity with low cost and high performance, this approach is obviously gaining more and more popularity.
