In particular, a shipping container is provided, the shipping container comprising: a chassis; a door moveably mounted to the chassis, the door having an external surface and an internal surface; at least one slot antenna located at the external surface of the door; a tracking device having a radio transceiver, the tracking device located on the internal surface of the door; and, an antenna feed coupling the radio transceiver to the slot antenna through the internal surface of the door. ## Claims ### Claim 1 A shipping container comprising: a chassis; a door moveably mounted to the chassis, the door having an external surface and an internal surface; at least one slot antenna located at the external surface of the door; a tracking device having a radio transceiver, configured to determine a location of the container and wirelessly provide the location to a remote device, the tracking device at least partially located on the internal surface of the door; and, an antenna feed coupling the radio transceiver to the slot antenna through the internal surface of the door, wherein a feed point and a ground of the antenna feed comprises a pair of spring-loaded electrical connectors extending from a surface of the tracking device, and the coupling of the radio transceiver to the slot antenna through the internal surface of the door occurs using the spring-loaded electrical connectors. ### Claim 2 (depends on 1) The shipping container of claim 1, wherein the feed point and the ground of the antenna feed are each located at the internal surface of the door opposite the slot antenna on the external surface. ### Claim 3 (depends on 1) The shipping container of claim 1, further comprising at least one bracket attaching the feed point and the ground of the antenna feed to the internal surface of the door. ### Claim 4 (depends on 1) The shipping container of claim 1, further comprising one or more apertures through the door, the ground of the antenna feed coupling the antenna feed to the slot antenna through the one or more apertures. ### Claim 5 (depends on 1) The shipping container of claim 1, wherein the tracking device is attached to the internal surface of the door using one or more of a bracket and a protective cage. ### Claim 6 (depends on 1) The shipping container of claim 1, wherein the slot antenna comprises one or more of a cellular antenna, a GPS (Global Positioning System) antenna, and a GLONASS (Navigazionnaya Sputnikovaya Sistema) antenna. ### Claim 7 (depends on 1) The shipping container of claim 1, wherein the slot antenna comprises one or more slots in the external surface of the door. ### Claim 8 (depends on 1) The shipping container of claim 1, wherein the slot antenna comprises a plurality of slots, each configured to transmit and receive a respective set of frequencies. ### Claim 9 (depends on 1) The shipping container of claim 1, wherein the antenna feed comprises one or more antenna feeds each configured to convey a respective set of frequencies between the radio transceiver and the slot antenna. ### Claim 10 (depends on 1) The shipping container of claim 1, wherein the antenna feed is configured to convey a plurality of sets of frequencies between the radio transceiver and the slot antenna. ### Claim 11 A shipping container comprising: a chassis; a door moveably mounted to the chassis, the door having an external surface and an internal surface; at least one slot antenna located at the external surface of the door; a tracking device having a radio transceiver, configured to determine a location of the container and wirelessly provide the location to a remote device, the tracking device at least partially located on the internal surface of the door; and, an antenna feed coupling the radio transceiver to the slot antenna through the internal surface of the door, wherein a feed point and a ground of the antenna feed comprises a pair of electrical connectors extending from a surface of the tracking device, and the internal surface of the door comprises a pair of receptacles configured to mate with the electrical connectors. ### Claim 12 (depends on 11) The shipping container of claim 11, wherein the feed point and the ground of the antenna feed are each located at the internal surface of the door opposite the slot antenna on the external surface. ### Claim 13 (depends on 11) The shipping container of claim 11, further comprising at least one bracket attaching the feed point and the ground of the antenna feed to the internal surface of the door. ### Claim 14 (depends on 11) The shipping container of claim 11, further comprising one or more apertures through the door, the ground of the antenna feed coupling the antenna feed to the slot antenna through the one or more apertures. ### Claim 15 (depends on 11) The shipping container of claim 11, wherein the tracking device is attached to the internal surface of the door using one or more of a bracket and a protective cage. ### Claim 16 (depends on 11) The shipping container of claim 11, wherein the slot antenna comprises one or more of a cellular antenna, a GPS (Global Positioning System) antenna, and a GLONASS (Navigazionnaya Sputnikovaya Sistema) antenna. ### Claim 17 (depends on 11) The shipping container of claim 11, wherein the slot antenna comprises one or more slots in the external surface of the door. ### Claim 18 (depends on 11) The shipping container of claim 11, wherein the slot antenna comprises a plurality of slots, each configured to transmit and receive a respective set of frequencies. ### Claim 19 (depends on 11) The shipping container of claim 11, wherein the antenna feed comprises one or more antenna feeds each configured to convey a respective set of frequencies between the radio transceiver and the slot antenna. ### Claim 20 (depends on 11) The shipping container of claim 11, wherein the antenna feed is configured to convey a plurality of sets of frequencies between the radio transceiver and the slot antenna.
