Parametric study of Vivaldi antenna
2009 13th International Symposium on Antenna Technology and Applied Electromagnetics and the Canadian Radio Science Meeting, 2009A parametric study of a wide-band Vivaldi antenna is presented. Four models were simulated using a finite element method design and analysis package Ansoft HFSS v 10.1. The simulated return loss and realized gain of each model for a frequency range of 12 to 20GHz is studied.

Dual Vivaldi antenna for telecommunications
2018 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo), 2018a lattice of two Vivaldi elements for the frequency range 900-2700 MHz is considered. The antenna is modeled by method of moments in the FEKO software environment. The received results can be used by systems of telecommunications, radio monitoring and radars applications.

Vivaldi Coplanar-Antipodal Antennas
2020 IEEE Ukrainian Microwave Week (UkrMW), 2020The stages of refinement of the Vivaldi antenna, which has both coplanar and antipodal radiators, is given, which gives it an advantage over the known Vivaldi antennas. The electromagnetic simulation results obtained with the CST studio suite software were compared with the experimental results of the printed coplanar-antipodal antenna measurements ...
