A new tuneable MIMO antenna designed for multimode, multiband handsets in LTE deployments has been unveiled by the China Mobile Research Institute in partnership with SkyCross. The antenna covers 12 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 memorandum of understanding (MoU) to jointly pursue compact MIMO antenna design and implementation for multimode, multiband LTE handsets.
The design and implementation of the antenna was conducted by SkyCross using a software-configurable approach to tune the antenna frequency band coverage from 700 MHz to 2.7 GHz. Frequency band requirements were detailed by China Mobile. The final tuneable, multimode, multiband, MIMO antenna design was tested at the China Mobile Research Institute and TMC laboratories in Beijing and satisfies China Mobile’s performance requirements.
Compact, multiband MIMO antennas are a key element in executing multimode, multiband handset designs for global LTE deployments since 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 honoured 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 Chairman. “Multiband, state-tunable ST-iMAT MIMO antennas enable 4G wireless devices to support worldwide roaming without sacrificing performance or increasing antenna size.”
