Claim:
1. A system comprising: a container; a device located within the container, the device configured to communicate wireless signals at a plurality of particular frequencies; an internal antenna removably mounted to an internal surface of the container, the internal antenna comprising a first ground plane, a first dielectric substrate, and a first patch characterized by a particular shape designed to tune the internal antenna to receive and radiate signals at the plurality of particular frequencies; an external antenna removably mounted to an external surface of the container, the external antenna comprising a second ground plane, a second dielectric substrate, and a second patch characterized by a particular shape designed to tune the external antenna to receive and radiate signals at the plurality of particular frequencies; and an electrical connection between the internal antenna and the external antenna; wherein the system is configured such that the internal antenna is operative to receive a first wireless signal from the device and provide a first electrical signal based on the first wireless signal via the electrical connection to the external antenna, and radiate from the external antenna a second wireless signal based on the first electrical signal; wherein the system is further configured such that the external antenna is operative to receive a third wireless signal, provide a second electrical signal based on the third wireless signal via the electrical connection to the internal antenna, and radiate from the internal antenna a fourth wireless signal based on the second electrical signal; wherein at least one of the internal and external antennas is formed as a patch antenna; wherein the shape of the patch antenna is selected to tune the patch antenna to receive and radiate signals at one or more of the particular frequencies; and wherein the patch antenna includes a backplane and a patch that includes first and second slots formed in the patch so as to be parallel to each other.
