China Mobile Research Institute and SkyCross have demonstrated what is believed to be the world's first tunable, MIMO antenna design for multimode, multiband handsets in LTE deployments. The compact MIMO antenna, intended for worldwide LTE deployment, delivers 12 frequency bands ranging from 700MHz to 2.7GHz for TD-LTE/LTE FDD/TD SCDMA/GSM EDGE/WCDMA.

China Mobile believes the convergence of TDD and FDD and the support of multiband are important for the mobile industry to realize the global scale and global roaming capabilities of the LTE standard. Cooperating with industry partners, China Mobile has made great strides in the convergence of TD-LTE and LTE FDD. The "one standard, one network platform, and single-chipset solutions" vision has built a solid foundation for the development of a global LTE terminal.

Compact, multiband MIMO antennas are a key element in executing multimode, multiband handset designs for global LTE deployments. LTE band definitions cover nearly all the possible unpaired TDD and paired FDD frequencies that all mobile operators use around the world. With multiband MIMO antennas now in place, the mobile handset ecosystem can now move forward in developing the remaining multiband components including power amplifiers, filters and duplexers, switches, RFICs and front-end-modules.

"Our joint development effort with SkyCross has demonstrated that cost-effective, multimode, multiband antennas are technically achievable for global LTE handsets," said Bill Huang, general manager of China Mobile Research Institute. "We believe this demonstration will accelerate the development of universal handsets capable of roaming worldwide, as well as create the manufacturing volume to meet all operators' requirements."

"SkyCross is honored to collaborate with China Mobile on an initiative that is so important to the future of the wireless industry," said Ben Naskar, SkyCross CEO and chair. "Multiband, state-tunable ST-iMAT MIMO antennas enable 4G wireless devices to support worldwide roaming without sacrificing performance or increasing antenna size."
