Hello,
I am an electronics and telecommunication engineer and my major is wireless systems' design. So far I have designed many antennas and their related parts such as matching circuits, filters(lumped/distributed), power dividers, phase shifters, power amplifiers, etc..
I can help you with an array of antennas which are circulary placed so you can sense the signal and decide where does it come from with a microcontroller but I need more details such as,
-What is the frequency range or which frequencies have to be captured?
-What is the power expectations?
-What is the purpose of the product? So I can give better ideas or options.
Let me know and I will do my best to help you.
Best regards
