In this letter, a novel antipodal tapered slot antenna (TSA) for ultra-wideband (UWB) applications is proposed. A folded fin structure is employed in the design for realizing wider bandwidth. Generally, UWB antennas have difficulty in its miniaturization because the lower-limit frequency reaches to 3.1 GHz. The lower-limit is determined by its total fin width. The folded fins realize both the lower limit and a compact size. We demonstrate the wideband characteristics in experiments. Its dispersion characteristic is also measured and discussed.
