Electrodynamics of vivaldi antenna arrays
2017 Radiation and Scattering of Electromagnetic Waves (RSEMW), 2017Theoretical investigation of a two dimensional periodical Vivaldi antenna array is presented. The array model in form of a system of coupled slot lines with variable parameters is proposed. Integral equations that describe all array eigen modes: TE, TM, TEM are obtained and solved.

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.

Review of reconfigurable vivaldi antennas
2010 IEEE Antennas and Propagation Society International Symposium, 2010In recent trends, the developments of multi-mode terminals have received great attention and have increased in popularity. Single terminals or devices could have many applications such as, GPS, GSM, WLAN, Bluetooth, etc. To suit such applications wideband, multi-band or reconfigurable antennas have been developed.

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 ...

A novel stealth Vivaldi antenna
2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2012A novel stealth Vivaldi antenna is proposed in this paper that covers the entire X-band from 8 to 12 GHz. Based on the difference of the current distribution on the metal patch when the antenna radiates or scatters, the shape of the patch is modified so that the electromagnetic scattering is significantly decreased in a wide angle range within the ...

IEEE Transactions on Antennas and Propagation, 2011
A novel Vivaldi antenna with added switched band functionality to operate in a wideband or narrowband mode is presented. The antenna reconfiguration is realized by inserting four pairs of switchable ring slots into the ground plane of the structure. A wide bandwidth mode from 1.0-3.2 GHz and three narrowband modes can be selected.
