A conventional wave distribution system distributes microwaves from a single Aperture Antenna. This Aperture Antenna has high efficiency but low distribution capacity. In this case, microwaves are concentrated to a particular part of the food. To overcome this problem, Samsung developed TDS, which cooks every part of the food evenly with an Aperture Antenna as well as two additional slot antennas so that waves can be more widely distributed. Efficient emission of microwaves translates into better cooked food. Models with this triple distribution system will bring the benefit of more even cooking to customers unhappy with the performance of their old microwave ovens.
