摘要
提出了在现有GSM移动通信系统中蜂窝基站采用波束转换智能天线的设计方案,对天线系统各组成部分如天线模块、收发射频模块、射频交换矩阵模块、高速扫描接收机等功能、作用、信号关系、设计要点作了探讨。若将各相邻小区配置波束转换智能天线,可有效提高网络的载噪比。
In this paper, we introduce the design of switched beam antenna＇used in cellular base station of current GSM mobile communication system, discuss the function, purpose, signal relation, design point of all components such as antenna module, Rx/Tx RF module, RF exchange matrix module and high-speed scanning receiver. If every adjacent cell in the system is installed the switched beam antenna, the carrier-to-interference-ratio of network can be improved significantly.
