Design and Analysis of Vivaldi Antennas
2018 International Conference on Innovation in Engineering and Technology (ICIET), 2018The antenna plays a vital role for signal transmission and reception in communication systems. Interestingly, the Vivaldi antenna is one of the promising arrays as it can be used for large bandwidth coverage and different emerging applications. Driven by this motivation, the main aim of this research is to design and analysis the Vivaldi antennas which

Bent antipodal Vivaldi antenna
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014A bent antipodal Vivaldi antenna with a -6 dB bandwidth from 150 MHz is presented. The whole antenna is realized on a 600 × 600 mm 2 silicone substrate. In this paper we describe the design, the realization and the performances of this antenna. This one is easy to make and does not require matching network or balun.

2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019
A very wideband uniplanar quasi-Vivaldi antenna is presented. Based on its easy fabrication, low cost, and wideband high gain performance, it appears suitable for imaging and other useful applications. It consists of a coplanar waveguide feed, and a pair Vivaldi patches. It exhibits a 10 dB reflection coefficient bandwidth of 1.9 GHz - 20 GHz.

Vivaldi Antennas for Microwave Imaging: Theoretical Analysis and Design Considerations
IEEE Transactions on Instrumentation and Measurement, 2006 The geometrical and electrical features of the Vivaldi antenna are studied in the light of the frequency-independent antenna theory. A scaling principle is derived for the exponential tapering of the antenna, and a closed-form model for the current ...
