Application of an Impedance Tuning Network for Mobile DVB-H Terminals

This paper presents the application of a reconfigurable impedance tuning network for a mobile DVB-H terminal. These kind of networks are becoming widely used in wireless communication systems to improve its efficiency. On the other hand, antenna design in DVB-H terminals is challenging due to the size limitation and as a result, the antenna presents large mismatches. To address this issue, we propose the use of a reconfigurable tuning network to reduce the mismatch (or the antenna size for a given mismatch) between the antenna and the RF front-end in a DVB-H terminal. This technique offers some advantages over other proposed alternatives and improves the antenna realized gain, as well as the efficiency of the DVB-H receiver.
