I'm trying to build a system that can detect the direction of a set of radio beacons operating on the same frequency.
In order to do this I have planned to use a normal radio antenna placed inside a faraday's cage that has an open side. Could this work?
I have tried to search for directional radio receivers but they tend to also receive some signal from the sides, which will interfere when multiple beacons operate on the same frequency, or they use multiple antenna’s/the Doppler effect. Both will also interfere with the frequency of the antenna.
So, can we make an effective directional radio detector using a radio receiver inside a faraday's cage with one side open mounted on top of a Stepper motor ?
