900MHz无线通信模块的仿真与设计

Wireless Communication Module Simulation And Design of 900MHz

以STC89c52单片机设计主控模块,以TI公司的cc1100芯片设计无线发射和接收模块,工作于915MHz ISM频段,空中波特率为100Kbps,利用HFSS仿真软件设计微带天线并进行仿真,得到S参数、驻波比、场强、三维远场辐射方向图等。同时利用smartRF studio软件可测得天线场强,实际效果好于仿真结果,实现了915MHz无线通信,通信距离在10米以上。

In this dissertation, STC89c52 is selected to design the main control module and TI＇cc1100 chips are chosen to design radio frequency and receive module, it works in 915MHz ISM band, and the baud rate is 100 Kbps. The HFSS simulation software is using to design and simulate the antenna, then getting the S parameters, VSWR, field, the direc- tion of three-dimensional far-field radiation patterns and so on. Simultaneously, the smartRF studio is using to measured the field of antenna, and goog actua result compared with the simulation. This finally realized 900MHz wireless communi- cation, and the transmission distance is above 10 meters.
