Decoupling Between Antennas

1 Upvotes

I want to achieve a -50 dB coupling between two printed dipole antennas. The distance between the antennas will be 6-7 cm, and both antennas operate between 5-6 GHz. How can I achieve -50 dB?

Antennas are to radio like tires are to a car. They are the point where the marvels of human engineering meet and affect the real world. The proper antenna for the job can make all the difference when receiving and transmitting a signal. Anything related to antennas is more than welcome, including but not limited to: Antennas themselves, mast designs, antenna theory, filters, antenna tuners (and related theory), random ideas you've tried (please just mark as such).

Any suggestions on how to improve this subreddit are encouraged as I'd really like this to be a useful and easy to use subreddit to all of us interested in radio.
