Vivaldi-based UWB Monopulse-Antenna
2010 International ITG Workshop on Smart Antennas (WSA), 2010This article describes a design of an UWB-Monopulse Antenna. A creation of the sum and difference beams is achieved over the large bandwidth from 3 GHz till 11 GHz. The distribution of the peak value of the impulse response over the angle around the antenna is calculated from the measurements.

Gain enhancement of antipodal vivaldi antenna
2018 26th Signal Processing and Communications Applications Conference (SIU), 2018Due to the broadband requirements in the field of communication, Ultra-Wide Band antennas have become popular nowadays. In this study, an antipodal Vivaldi antenna with UWB and compact design was investigated for X band applications. The antenna features have been developed using Defective Ground Surfaces (DGS) and dielectric lenses.

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.

2016 International Conference on Communication and Electronics Systems (ICCES), 2016
In this paper, the authors has presented a design of Antipodal Vivaldi Antenna for the scopes of UWB applications. The proposed antenna has been designed to explicit operational frequencies from 2.5 GHz to 30 GHz where the sub-bands covers from 3.1 GHz to 10.6 GHz for the case of UWB and beyond 10.6 GHz for the case of Super UWB. Throughout this entire

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 ...
