PURPOSE: A resonance structure for microwave lighting fixture is provided to improve the intensity and the opening ratio by forming the hexagonal netlike structure of the mesh area of a resonance. CONSTITUTION: The cylindrical resonance(103) of the microwave lighting fixture comprises a hexagonal netlike mesh area(301), a surface area(302) made by thin film, and a reflecting mirror(119) placed between the mesh area and the surface area. The hexagonal netlike mesh area guarantees the high opening ratio and improves the intensity rather than the square type mesh area.
