Abstract
The Vivaldi antenna is a kind of wide band antenna, which is widely used in many wide band electronic systems. This paper designed and fabricated a specific antipodal Vivaldi antenna (AVA) for practical application. The operating frequency range of fabricated AVA is from 2 GHz to 11GHz. The length and width of the fabricated AVA are 92.7millimeter and 110.4millimeter, respectively. A practical AVA was fabricated according to simulation parameters. The experimental results of the AVA are provided and analyzed. For the fabricated AVA, the measured average voltage standing wave ratio (VSWR) is 2 and gains are higher than 0 dB within the operating frequency range. Meanwhile, the wide beam performances are also observed. The experimental research on the AVA can be as a technical reference for the design and implementation of other Vivaldi antennas.
