Greetings, we all know that apart from defected ground structure there are a lot more way to address coupling between the radiators in MIMO antenna. But making a complete split at ground plane directly disrupts the coupling. So, my question regarding the same is, is it wrong to work with completely unconnected ground plane. What are the pros and cons in usage of unconnected ground plane in printed MIMO antennas. (necessary image of 2 element mimo antenna with unconnected ground is included)
