The most common form of interaction is parasitic and takes the form of effectively changing both the impedance and electrical wavelength of the antenna. This is a lot more complex set of interactions than is worth going into here but hopefully it will suffice to say that in erecting various forms of antennas over the years, we have found that virtually any material in close proximity to an antenna has an effect.
You will not find any measurable temperature change.
