MICROWAVE OVEN HAVING L-SHAPED ANTENNA

摘要

MICROWAVE OVEN HAVING L-SHAPED ANTENNA A microwave oven has a rotary antenna of substantially L-shaped configuration from which microwaves are radiated into a heating cavity. This antenna is constituted by a first antenna portion which extends perpendicularly from a wall of the heating cavity and has a length substantially equal to a quarter of the wavelength, and a second antenna portion which extends parallel to the wall and has a length substantially equal to half the wavelength. The arrangement improves over prior microwave ovens by radiating microwaves in two perpendicular directions and, as a result, distributing the microwaves more evenly inside the heating cavity. Excessive heating of the shelf supporting the food is avoided, the full power of the energy being applied to the food.
