摘要
根据天线的优化设计原理,提供了一种由电磁仿真软件模拟单极子天线在50Ω输入阻抗的匹配过程。与传统天线由理论设计到真实环境匹配过程不同,运用软件自带集总RLC功能,在不改变天线规模的情况下,模拟了单极子天线在真实电阻、电容与电感环境中的特性,且通过平参数扫描这一便利功能,使其能够快速在目前无线传输模块广泛适用的868 MHz频率下达到最佳匹配效果。结果表明,所提方法能够有效简化天线的生产环节,大大降低了天线的研究门槛。
According to the optimized design principle of the antenna,a matching process of the monopole antenna in 50 Ω input lmpedance is simulated by the electromagnetic simulation software.Different from the matching process of traditional antenna from theoretical design to real environment,the software uses the lumped RLC function to simulate the characteristics of monopole antenna in the real resistance,capacitance and inductance environment without changing the antenna scale.And through the convenient function of flat parameter scanning,it can quickly achieve the best matching effect at the 868 MHz frequency widely used in current wireless transmission modules.The experiment results indicate that the proposed method could effectively simplify the production of the antenna and greatly reduce the research threshold of the antenna.
