I have multiple Yagi antennas horizontally polarized. They are all placed in closed proximity at the same height horizontally and operating in a similar frequency.
The yagis are 2.45GHz, bluetooth band, so they are quite small in size. There is an array of them (PCB antennas) mounted in a radial array of 180. The back of the antennas are very close together, like an 1" apart. The purpose of this design is to be able to gather where a signal is coming from. Is there a way to make them so directional or introducing an element, such as a metal panel that would prevent them from overlapping?
The back lobe from the antenna's is overlapping with the from lobe with other antennas. I'm wishing to be able to prevent that.
The only idea that does to mind but I don't know if it would work is to place a solid piece of metal, grounded, in between the antennas.
Will this work? Are there better ways of creating this antenna to antenna isolation?
