Multi band, multi antenna system for modern mobile terminal

A compact, multi-band, multi antenna system was designed and optimized. It has compact size, good performance, good isolation and is very cost effective. MoM is successfully used in the antenna design and optimization. The results agree well with the measurements. The extension of the antenna work was done, to have this kind of antenna system as a GSM/DCS/PCS/UMTS version and a 850/900/1800/1900 quad-band version as well.
