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

Design of Low-RCS Vivaldi Antenna Based on Characteristic Mode Analysis
IEEE Antennas and Wireless Propagation LettersIn this letter, a low radar cross section (RCS) Vivaldi antenna is designed based on characteristic mode analysis (CMA). The characteristic mode theory (CMT) is first applied to wideband RCS reduction of the Vivaldi antenna.

Ultrawideband Circularly Polarized Halved-Type Vivaldi Antenna With Symmetrical Radiation Pattern
IEEE Antennas and Wireless Propagation LettersIn this letter, a novel ultrawideband circularly polarized halved-type Vivaldi antenna (HVA) with symmetrical radiation patterns is presented. As we know, conventional HVAs have the drawback of asymmetrical E-plane radiation patterns and the need for an ...

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.

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 ...
