Most LoRa boards come with prebuilt antennas, which are unoptimized and flawed.
In this workshop you will learn the basics about Radio-Antennas, build your own antenna, test it and optimize it for the LoRa frequency band.
This workshop will give an introduction into the radio antenna theory.
You can build then your own antenna, which is optimized for the LoRa frequency band.
You will also test and tune your antenna to have optimal radio characteristics and will beat most of the stock-sold antennas.
This workshop includes basic crimping and soldering, which will be introduced and can be done by everybody.
The material for the workshop will be provided.
Bring your LoRa devices and Antennas to the workshop.
You can measure and optimize your antennas and optimize them as well.
