I am looking for some information on antenna coupling.
I am looking at coupling energy from one transmitters antenna into another antenna. Basically instead of using the antenna on the transmitter itself, I need to use the second antenna.
This is for a project at work. I designed a second antenna resonant at the same frequency as the transmitter. This second antenna was basically a number of loops of wire wrapped around the first antenna (they were isolated by plastic).
The transmitter is placed in a metal box with the second antenna protruding through the metal box. I was able to make this work, but the problem I am faced with is the math behind it. I would like to put together information on how this is done. This is basically like a transformer coupling, but done at 434 MHZ.
Can anyone provide some information
