MIMO技术今后将会成为便携式无线设备的标准功能,并对天线设计提出很大挑战。如果没有更先进的技术,天线将会成为无线设备在尺寸、外观、性能等方面的瓶颈。为了解决上述问题.除原有的天线生产厂商外,半导体、设备厂商也开始涉及这一领域。厂商的应对方案主要包括:采用特异材料.采用极为微细的天线,结合采用可调谐天线技术与控制技术。另外,软件无线电与认知无线电技术的研发工作也正在进行。
MIMO technology will become the standard feature of portable wireless devices in the future and pose a great challenge to antenna design. Without more advanced technology, the antenna will be a bottleneck in terms of size, appearance, performance and more. In order to solve the above problems, in addition to the original antenna manufacturers, the semiconductor, equipment manufacturers are also beginning to be involved in this area. Manufacturers to deal with the program mainly include: the use of special materials using a very fine antenna, using a combination of tunable antenna technology and control technology. In addition, software radio and cognitive radio technology research and development work is also underway.
