Abstract

Electrically small antennas typically suffer from a low radiation resistance, efficiency and bandwidth. In particular, achieving a high directivity (often called superdirectivity) from these structures is especially challenging, often requiring arrays which are extremely sensitive to mechanical and electrical tolerancing. Nonetheless, it was recently discovered that superdirectivity could be achieved by an electrically small gold nanoloop. Unfortunately, the initial design suffered from poor efficiency. A thicker nanoloop exhibits higher efficiency at the expense of a shift in the frequency range of high directivity to a region where the loop is no longer electrically small. This paper will explicitly show the tradeoffs between size, directivity and gain for nanoloops through a series of multi-objective optimizations.
