摘　　要：在阐述了小型移动终端天线传统设计思想的基础上,考虑到人体影响及比吸收率(SAR)问题等因素,讨论了天线设计改进的途径如采用平衡结构等;并针对现代移动通信系统的要求讨论了自补偿天线、一体化以及软件天线等新的天线设计思想,为小型移动终端天线的近一步研究提供参考。Based on the conventional design concept of antennas, some methods such as balanced structure are discussed to relieve the degradation of the antenna's performance due to the human-body effect and to overcome the SAR problems. Referring to the trends in modern mobile communications and the demands for antennas, the more-advanced concept is discussed such as self-complementary antennas, the application of integration technology to antenna system and software antenna.
