基于ESP32芯片的天线性能研究

Research on Antenna Performance Based on ESP32 Chip

针对基于ESP32芯片的天线性能明显不足的现状,使用天线仿真软件对倒F蛇形天线和半波偶极子天线两款常用天线进行了辐射特性仿真,并改进了一个轻量化的网络性能测试工具,通过实验对比了其在辐射特性、接收信号强度指示以及吞吐量方面的表现。在软件协议栈方面,使用网络性能测试工具对LwIP协议栈进行了内存参数修改,以提高其在使用TCP协议时的网络吞吐量性能,通过实验对比实现了较好的优化效果。

In response to the significant lack of antenna performance based on the ESP32 chip,antenna simulation software is used to simulate the radiation characteristics of two commonly used antennas,the inverted F snake antenna and the half wave dipole antenna.A lightweight network performance testing tool is improved,and its performance in radiation characteristics,received signal strength indication,and throughput are compared through experiments.In terms of software protocol stack,network performance testing tools are used to modify the memory parameters of the LwIP protocol stack to improve its network throughput performance when using TCP protocol.Through experimental comparison,good optimization results are achieved.
