Recently, modern mobile handsets are miniature in size, and they are required to operate at multiple-frequency bands in order to provide the enhanced and multi-functional performances. Further, due the device convergence rends in the mobile handset, very limited space is available for the antenna structure. The conventional passive multi-band antennas often require large size of antenna dimension. Moreover, passive multi-band antennas might be less efficiency in term of minimize or eliminate unwanted radio frequency interference and/or reducing the adverse effects of co-site interference and jamming.
