Abstract
A wireless communication device and method for identifying a container or communication information about a container using a slot in the container as an antenna. The device includes a wireless communication device for transmitting information regarding the container. The container includes an outer wall forming rim and a slot between the rim edge and the outer wall that is circular and continues without boundaries. The wireless communication device is coupled to the slot to provide the slot antenna for communications. An impedance matching network is additionally provided to make the operating frequency of the slot the same as the operating frequency of the wireless communication device. Alternatively, shorting posts may placed in the slot to define boundaries of the slot to match the operating frequency of the slot to the operating frequency of the antenna.
