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 ...

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

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.

Vivaldi antenna arrays for SKA
IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002We present several broad band arrays of tapered slot antennas for use in a new generation phased array telescope. In specific, a four element linearly polarized 3-12 GHz array, a 3 element 0.8-2.5 GHz coupled array and a four element dual polarized 0.8-2.5 GHz array are discussed. Integration with LNAs and coupling between elements is examined.
