<p>The present invention relates to a heating apparatus using a micro-cavity antenna and, more specifically, to a heating apparatus comprising: a heating chamber including a heating space part inside; a supply part installed to pass through the heating space part of the heating chamber to supply water for heating; multiple antennas installed along the outer periphery of the heating chamber to heat supplied water by heating the supply part by radiating a microwave to the heating space part; and a blowing part to blow hot air by increasing the temperature of air supplied by heat exchanging with the supply part heated by blowing air in order to pass through the heating space part. The present invention has effects of increasing an amount of heating by increasing a heating space part as multiple antennas are installed in a plane forming an outer shape of a heating chamber, preventing a stop by being interfered by a microwave transmitted from other antennas by transmitting only a microwave generated by a corresponding magnetron to the outside by forming a slot of each antenna to cover an open space of a waveguide space part, and improving heating efficiency by supplying hot air by a blowing part.</p> |
