An ultra-wideband (UWB) slotted compact Vivaldi antenna with a microstrip line feed was
evaluated for microwave imaging (MI) applications. The recommended FR4 substrate-based …

A wideband phased array antenna consisted of all-metal Vivaldi is designed in this paper. It
is a line array with 8 Vivaldi elements, at the ends of the array there are two additional …

This paper has introduced the concept of UWB antenna in array arrangements. The four
elements of Balance Antipodal Vivaldi Antenna (BAVA) has been used for planar and H …

This article presents the comparative analysis of antennas for Ground Penetration Radars
(GPR) that operate in the VHF/UHF band around 200 MHz. Three types of antennas are …

This paper presents the results of two methods of improving the radiation characteristics of a
Vivaldi antenna in phased array. The effect of cutouts and rectangular inserts along sides of …

In this paper, we propose an Ultra-wideband Balanced antipodal Vivaldi antenna embedded
with equal rectangular shaped fins (RF-BAVA) for wide-band imaging application has been …

In this paper, an Ultra-wideband Balance Antipodal Vivaldi Antenna in planar and h-plane
array configuration is presented. The comparison of four elements of BAVA array in both …

This paper presents the novel design of an ultrawideband (UWB) antipodal Vivaldi antenna
using periodic elliptical slots (PES-AVA) for microwave and radar imaging applications …

Антенна Вивальди, впервые представленная Петером Гибсоном в 1979 году [1],
