A reconfigurable Radio Frequency Identification (RFID) antenna assembly utilizing a common reflector core includes a plurality of antennas (10), wherein each antenna consists of a first replaceable antenna element (20), at least one first replaceable standoff (22), and a reflector panel (24), which is configured for a lowest operable frequency of the antenna assembly. The reflector panels of all the plurality of antenna elements are connected together to form a common reflector core housing within the antenna elements disposed outside of the housing. The first replaceable antenna element the first replaceable standoffs, and the common reflector core are configured for a first operating frequency of the antenna assembly. The first replaceable antenna elements and first replaceable standotfs are replaceable on the common reflector core with second replaceable antenna elements and second replaceable standoffs operable at a second frequency.

An antenna 10 comprises at least a first pair 12 of elongate radiating elements and a second pair 14 of elongate radiating elements. Each pair comprises a first element 12.1 and a second element 12.2. Each element has a feed end 12.11 and a distal end 12.12. The first and second elements of each of the at least first pair and second pair have their respective feed ends 12.1 1, 12.21 in juxtaposition relative to one another and extend in diverging relationship relative to one another in a direction from their feed ends towards their distal ends. The at least first and second pairs are electrically connected in parallel. In some embodiments the elements may diverge exponentially. The invention also relates to antennas which may be packaged in at least partially knock-down form to be assembled or deployed conveniently at a user site.

In one embodiment, a radio communication system comprises a removable antenna platform and an antenna interface bulkhead connected to a roof of a locomotive. The antenna platform includes a blind mate connector connected to an antenna mount. The antenna mount is connected to a ground plane. The antenna interface bulkhead includes a blind mate connector configured to mate with the blind mate connector of the antenna platform when the antenna platform is attached to the antenna interface bulkhead. The antenna interface bulkhead is configured to attach to the antenna platform in one orientation. Thus, one or more antennas may be quickly attached to or removed from the roof of the locomotive reducing maintenance time for the locomotive when an antenna upgrade may be desired.
