Abstract
An antenna for protecting radio frequency communications includes a masking portion to broadcast a masking signal including a first loop and a second loop connected to the first loop, wherein a current supplied to the masking portion flows in opposite polarity in each of the first and second loops. The antenna includes a reader loop to receive a response signal from a responder and decoupled from the masking signal, wherein the masking signal masks the response signal about the responder.
