摘要
在TPMS系统中,天线性能的好坏直接影响无线通信的效果。倒F螺旋天线具有全向性、增益高的特点。针对倒F螺旋全向天线进行研究与设计,用电磁仿真软件CST对天线模型进行了设计与仿真,并根据优化结果制作了实物模型。测试结果表明:谐振频率为433MHz,回波损耗为-19.49dB,测试结果与仿真结果吻合良好。
In the TPMS system, quality of antenna performance immediately influences effect of wireless communication. Aiming at the problem of inverted F helical antenna, this article conducts to research and design. With the CST Microwave Studio software, antenna is simulated and designed, the antenna is omni directional with -19.49 of reflection loss and 433 MHz of harmonic frequency, a model is built and is tested by network analyzer, the testing results agree very well with the simulation result.
