One place to begin asking this question is with antenna theory. The basic question you are asking is what does the radiation pattern of a mobile phone antenna or wifi router antenna look like if you put a huge plane of metal above it. There are debian packages like nec and xnecview for antenna modeling. Some of these only allow you to create wire elements, but some allow grid or planar elements. Getting an answer that you believe out of these modelling programs is tricky.
