摘要:

针对移动终端内置天线的高性能结构技术、小型化技术、多波段技术等,综合给出了近年来各种移动终端内置天线的主要研究方向及其应用特点。并分析了天线结构、组合方法、带宽增强、加载等影响高性能内置天线的主要关键技术。同时,基于实际移动终端天线研制的实践,给出了小型、多波段和高性能终端内置天线所面临的难点和解决问题的有效方法。研究结果表明,虽然先进加工工艺推动了小型化2-3波段天线的可实现性,但3个波段以上内置天线的设计将主要依赖天线组合技术。可以预见,不断出现的先进终端天线技术将推动移动终端的广泛应用,以满足无缝、泛在无线移动通信网络发展的需要。

Abstract:

Abstract: High performance structure technology, miniaturization and multi-band methods of internal antenna were investigated. The main research orientations and application characteristics of internal antenna in recent years were summarized. The key technology in the design of high performance internal antennas of mobile terminals such as antenna structured method, combinatorial method, bandwidth enhancement, and loaded method were investigated and analyzed. Meanwhile, based on the practices of actual internal antenna production, we discussed the difficulties in miniaturized, multiband and high performance internal antennas and provided some effective solutions. The research indicated that the advanced manufacturing technology has promoted the implementation of the 2-3 bands internal antenna, however, the implementation of three or more bands should mainly depend on the combinatorial method. Predictably, the new technology of internal antenna is coming to the fore which will promote wider application of mobile terminals and meet the future demand for development of seamless, ubiquitous mobile radio communication network.
