Metamaterials (MTMs) are artificially engineered materials with unique electromagnetic
properties not occurring in natural materials. MTMs have gained considerable attention …

The increasing proliferation of advanced devices for UWB, 5G communication, micrometer-
wave, and millimeter-wave communication demands an antenna which can handle huge …

The generation today is heading toward 5G technology and hence lot of research work is
carried out in the field of antenna design in terms of compact antenna designs, bandwidth …

An ultrawideband metamaterial slab (meta-slab) covered antipodal Vivaldi antenna (AVA)
with high-gain and stable radiation patterns is presented. The meta-slab exploiting the …

A novel compact Vivaldi Antenna (CVA) for short-pulse ground penetrating radar (GPR)
systems is presented. Artificial materials lens (AML) and sidelobe suppressor (SSR) are …

In this article, an ultra-wideband metasurface lens is designed and integrated into an
antipodal Vivaldi antenna (AVA) to improve its radiation directivity without affecting its …

In this research article, a wideband antipodal Vivaldi antenna (AVA) is presented by
incorporating a negative index metamaterial (NIM). The proposed antenna is designed …

In this paper, the gradient elliptical slots (ES) are designed to enhance the operating
bandwidth of the Vivaldi antenna (VA) in the relatively low frequency band. The antenna …

An antipodal Vivaldi antenna with a compact parasitic patch to overcome radiation
performance degradations in the high-frequency band is proposed. For this purpose, a …

This study involves the integration of a compact Antipodal Vivaldi Antenna (AVA) with a
square-shaped split ring resonator (SSRR) metamaterial to achieve improved performance …
