Claim:
1. A compound coupler, comprising: a first compound loop antenna connected to an electrical circuit, the first compound loop antenna including at least a first radiator element and a first loop element; and a second compound loop antenna connected to a re-radiator antenna, the second compound loop antenna including at least a second radiator element and a second loop element, the second compound loop antenna being placed in close proximity to, but not in direct contact with, the first compound loop antenna, wherein the first compound loop antenna compound couples with the second compound loop antenna to wirelessly transmit RF energy from the electrical circuit to the second compound loop antenna for transmission by the re-radiator antenna, wherein the compound coupling between the first compound loop antenna and the second compound loop antenna is simultaneously capacitive and inductive, and is associated with a coupling efficiency that is not highly sensitive to translation and alignment between the first compound loop antenna and the second compound loop antenna.
