Abstract
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 planes has been observed. Each element
of an antenna printed on the glass-reinforced epoxy laminate
material (FR4) with a thickness of 1.5mm and relative
permittivity of 4.3. The dimension of every single element is
60.75mm x 66mm approximately. The array elements of both
planes almost cover the whole UWB frequency range with the
reflection coefficient of -10dB. Based on the simulation results,
the array elements in planar configuration showing good
reflection and works well at 3.2GHz frequency while the
configuration in h-plane the array elements works well at
7GHz of frequency. In planar configuration, the operating
frequency of antenna elements is shifting as a result of the
distance between inter elements which intensification in
wavelength. The array elements in h-plane produce more gain
up to 10.2 dB with good radiation patterns as compared to the
planar plane. The antenna design and optimization
development are verified using CST simulation software
