China Mobile, SkyCross show LTE multiband MIMO antenna

China Mobile Research Institute and antenna company SkyCross have demonstrated a tunable, MIMO antenna design for multimode, multiband handsets in LTE deployments around the globe. The tunable MIMO antenna covers twelve frequency bands ranging from 700 MHz to 2.7 GHz for TD LTE/LTE FDD/TD SCDMA/GSM EDGE/WCDMA deployments worldwide. In September 2010, China Mobile Research Institute and SkyCross signed a joint MoU to jointly pursue MIMO antenna design and implementation for multimode, multiband LTE handsets. China Mobile provided detailed requirements for global frequency band combinations needed including TD LTE/LTE FDD/TD SCDMA/GSM EDGE/WCDMA for potential global LTE and legacy network co-deployment, as well as target global roaming bands. China Mobile also provided detailed antenna performance requirements meeting 3GPP specifications. SkyCross conducted all the antenna design and implementation using a software-configurable approach to tune the antenna frequency band coverage from 700 MHz to 2.7 GHz. The final tunable, multimode, multiband, MIMO antenna design was tested at the China Mobile Research Institute and TMC laboratories in Beijing.
