Abstract

An antenna is provided having an integral balun (202) that together with a transmission medium forms a radiating structure for the antenna. In accordance with an exemplary embodiment of the invention, an antenna in the form of a resonant-loop antenna is provided for use in an RFID reader system. A balun is provided with the resonant-loop antenna in the form of a gap or separation in a portion of a transmission medium (201A, 201B) (e.g., coaxial cable, microstrip, etc.).
