As it is known, for 5G (the 5th generation mobile communications), there are two frequency segments, the millimeter-wave (mm-wave) one and the micro-wave (i.e., non-mm-wave) one; also, antennas are crucial to the wireless communication performance. Currently, in 5G mobile phones, the mm-wave and non-mm-wave are separate and the antenna numbers are much more than those in 4G mobile phones. To reduce the occupied volumes by antennas in 5G phones, the integrations of mm-wave and non-mm-wave antennas to achieve the total solution of 5G antennas to enhance competitiveness of mobile phones have attracted strong and wide interest and researches from the industry and academia. In this presentation, several innovative and inspiring integration solutions (including the module type, FPC type, exterior type, and display type) of mm-wave and non-mm-wave antennas are systematically retrospected and prospected. Furthermore, the integration evolution is also analyzed to benefit and enlighten the future developments.
