2020年3月12日 · Using an external antenna can solve problems related with slow video streaming web servers and other connectivity problems. This tutorial shows how to use an external antenna with the ESP32-CAM. The ESP32-CAM has the option to use either the built-in PCB antenna or an external antenna as the one shown in the following figure.

Adding an external antenna to a non-antenna ESP module. Most of ESP32 and ESP8266 modules have no antenna connectors, but you may still add an antenna. At first, it seems to be difficult to figure out exactly what to do, but Espressif Systems blueprints reveal how to switch to an external antenna, if you haven’t got an external antenna ready ...

Sometimes you need an external antenna for the ESP8266. For example you want to install the ESP into a metall box for some outside or other applications which is installed in cases. Or you only need a more signal strength.

2019年8月13日 · If you’ve purchased an ESP board without a connector for an external antenna and find you are pushing the limits of reception - all is not lost. Also this is slightly easier than moving the 0603 sized resistor required to use the external antenna socket on some boards. These parts can be found for a couple of dollars on ebay or Aliexpress:

While the ESP32 comes with an on-board PCB antenna, there are many scenarios where an external antenna can significantly improve wireless performance. This article will guide you through the process of designing an external antenna for your ESP32 board, covering everything from basic concepts to advanced techniques and regulatory considerations.

2021年10月14日 · When experimenting with ESP32 modules, especially the ESP32 CAMs, I wish I had a little more WIFI range reserve. This could be achieved by adding an external antenna – but only a few modules are prepared for the connection of an external antenna.

ESP32 多根天线功能主要包含 3 个部分：芯片内部的 PHY 天线模块、IO MUX 和 GPIO Matrix、以及外部的天线切换器。 1.芯片内部的天线选择模块 PHY Antenna Module： 两个天线模块均支持工作于发送 (TX) 或接收 (RX) 模式，可以通过软件配置发送和接收选用某个模块。 每个天线模块最多支持输出 4 个天线选择信号 antenna_select [3:0]，该信号值可由软件配置并且可以一一映射到任意 IO 引脚。 当某个天线模块处于工作状态时，IO 引脚的高低电平值为软件配置的信号值。 …

In this tutorial, we will explore the hardware design process for integrating a PCB antenna with the ESP32, covering essential concepts, design considerations, and best practices. What is a PCB Antenna?

ESP32 With External Long Distance Antenna: Today’s topic concerns a distance test with an ESP32 with External Antenna. Let's use two modules today: from Espressif and TTGO. Let's then check the RSSI between these two ESP32 antennas, generate a graph from the history, and write a …

2023年1月7日 · How to design custom hardware using ESP32 MCUs (ESP32-C3, NOT pre-made modules!) and PCB antennas (inverted F, in this case).
