1. A system for treating a skin tissue of a patient comprising:
a microwave energy generator;
an array of microwave antennas configured for placement proximate to the skin tissue, wherein the array of microwave antennas includes one or more waveguide antennas with a cross-sectional size configured to a desired operational frequency and with a field configuration of a waveguide depending on a desired clinical objective and a geometry of a particular anatomical area to be treated;
a cooling plate configured for placement in contact with the skin tissue and protectively cool a layer of skin above a target layer;
a cooling fluid circuit configured for placement adjacent to the cooling plate, wherein the cooling plate further comprises a flow chamber configured to retain a liquid coolant between the cooling plate and the array of microwave antennas; and
a suction element configured for elevating the skin tissue and placing the skin tissue in contact with the cooling plate,
wherein the array of microwave antennas is configured to deliver microwave energy to the skin tissue sufficient to create a thermal effect in a target tissue within the skin tissue, and
wherein a distal end of the waveguide of the one or more waveguide antennas is operably connected to the cooling fluid circuit at least partially superimposed on the cooling plate.
