A refrigerator is provided to mount front and rear antennas in a refrigerator storage chamber for determining receiving and withdrawing of food according to sequence of wireless tag data detection from the antennas without manual input of food data. A refrigerator includes front and rear antennas(52,54) respectively mounted around an opening of a storing chamber of a refrigerator with a detection range approximately parallel to the opening, wherein the rear antenna is mounted at a rear part of the front antenna. A tag detection element(26) is connected to the front and rear antennas and drives the front and rear antennas after door switches detect door opening of the refrigerator. If wireless tag data are detected in the sequence of front and rear antennas, food receiving is determined by a controller. If the data is detected in the sequence of rear and front antennas, food withdrawing is determined. The controller is connected with the tag detection element and a wireless adapter(28).
