| Summary: | H-plane array configuration of different elements
of balance antipodal Vivaldi antenna is presented in this paper.
The configuration of an antenna is based on the improvement in
radiation characteristics of BAVA. The use of two and four
elements placed in h-plane configuration is considered. Each
single element antenna is printed on FR4 substrate of 1.5 mm
thickness with relative permittivity of 4.3. The dimension of each
single element is 60.75 mm × 66 mm approximately. The single
element of BAVA covers almost whole Ultra-wide band
frequency range with -10dB of return loss and an antenna works
well at 9GHz frequency with maximum bandwidth of 1.186 GHz
and respectable gain of 11.3 dBi. The elliptical shaped dielectric
director with permittivity similar to that of FR4 substrate is
implanted in an antenna aperture in order to intensify the
radiation pattern with low side lobe level and improved gain of
an antenna. In h-plane configuration the two and four elements
of antenna will be compared with modified version of BAVA. The
extensions in length of a substrate called director significantly
enhance the radiation characteristics. The design and
optimization development is proven viable via CST simulation
software. |
