Abstract

Abstract:

Based on the vivaldi antenna, we analyze the impendance bandwidth of the antenna affected by the tapered slot-line structure, and propose the method for improving and optimizing the antenna's structure by the way of adding slots on the metal patch. The results of the simulated data and measured data show that the VSWR is less than 2, with the bandwidth ranging from 320MHz to 1GHz, and between 1.16GHz and 1.3GHz. At the same time, the VSWR of the application bandwidth is 1.2. So the Vivaldi antenna has the excellent properties of high gain, miniaturization and wide-band.

Key words: tapered slot antenna, ultra-wideband, voltage standing wave ratio
