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...
Ultra wideband (UWB) is a wireless technology to realize high speed communications which is performed in a wideband. However, the dispersion characteristics of antennas change seriously in the wide frequency band. Distortion arising from the dispersion reduces communication quality. In this paper, we numerically analyze the dispersion characteristics of linearly tapered slot antenna (LTSA) and Vivaldi...
