Active integrated antenna radiating resonator have no enclosure, how stable is it?

I have seen many papers on AIAs (active integrated antennas). It uses radiating patch as resonator element in transistor feedback loop.
On the other hand usual RF systems with microstrip resonators have metallic enclosures over oscillator part.
As AIA have no any enclosure, and resonating patch is outside, is it possible that enviroment objects will alter frequency of AIA (somehow like varactor or tuning screw)?
