Mar 12, 2020 · The ESP32-CAM comes with an on-board Wi-Fi antenna, but it also has an IPEX connector if you want to use an external antenna. Using an external antenna can solve problems related with slow video streaming web servers and other connectivity problems.

An external antenna has far better characteristics than an inbuilt antenna on the upper part of an ESP module PCB. Find this and other hardware projects on Hackster.io.

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.

Aug 13, 2019 · 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.

When considering an external antenna for your ESP32 board, you have several options to choose from. Each type has its own set of characteristics, advantages, and limitations. Here’s an overview of the most common antenna types suitable for ESP32 applications: 1. Monopole Antennas.

2.4G 3DBI Gain WiFi Antenna with U.FL to Female SMA Cable for Arduino ESP8266 ESP32 ESP-07 ESP32-WROOM-32U

Apr 12, 2018 · With external antenna, we talking a proper dipole, with 2.15dBi gain, connected to the board with good RF method, you will get better range. What antenna are you using and how do you position them? Polarisation is important as well.

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 log of the values in a .csv file.

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?

Apr 14, 2018 · The best solution would be to use some 2.4 GHz antenna with coaxial cable terminated with U.FL connector (antenna must be positioned outside of the metal case). Antenna should also have 50 ohms characteristic impedance.
