Simulating Analysis of T-selection Impedance Matching Network of Antenna Turner in Matching Dipole Antennas

介绍了天线调谐器阻抗匹配网络的基本形式和参数配置;以一个T形阻抗匹配网络为例,对网络的匹配区域和匹配精度进行了仿真,分析了各参数对适用频段的影响,对比了理论值与实际值的差异;对不同尺寸的双极天线进行了适配仿真,对天线的适配频段、谐振频段和VSWR分布进行了分析与讨论。

This paper introduces the basic forms and parameter setting of impedance matching network of antenna tuner,takes a T-selection impedance matching network as an example to simulate the matching domain and the matching precision of the network,analyzes the influence of all parameters on usable frequency band,compares the difference between theoretical value and practical value,makes matching simulation on dipole antennas with different sizes,and analyzes and discusses the usable frequency band,resonance band and VSWR distribution.
