摘　　要：针对目前广泛使用的WCDMA系统中存在的多通信制式,先从理论上分析了多通信制式共存时干扰存在可能性,然后运用天线近场方程理论建立了WCDMA和WLAN两制式共存的终端模型。最后通过实际的仿真数据,给出了两制式共存系统避免彼此干扰的天线解决方案,在此基础上,又提出了多制式共存天线设计的具体措施和解决方案,为WCDMA移动终端中多通信制式共存终端设计提供了有利参考。For the coexistence of multi-communication modes in WCDMA system, this paper, based on QUALCOMM RF solution, theoretically analyzes and describes the possibility of interference resulted from the coexistence of multi-communication modes. Then by applying the antenna near-field equation theory, the terminal model with two modes of WCDMA and WLAN coexisted is contructed. Finally, in the light of actual simulation data, the antenna solution for two-mode coexistent system to avoid the interference resulting from two-standard coexistence is given, and with this, the specific measures and solutions for multi-mode system are suggested, which provide a favorable reference for the design of WCDMA mobile terminal system with multi-communication modes.
