A document presents a comprehensive overview of the technology of tapered-slot antennas and arrays of such antennas. The fundamental operation of tapered-slot antennas is not yet fully understood, and, for lack of established design rules, the designs of these antennas have been based primarily on empirical results. The document combines results of previous research and development with more-recent design information and measurement data to provide a better understanding of the fundamental operation of tapered-slot antennas and arrays. The better understanding provided by the document is intended to contribute to the establishment of design guidelines.
