Bandwidth Enhanced Antipodal Vivaldi Antenna for Wideband Systems

In this work a novel antipodal Vivaldi antenna is designed to operate between L to KU band communication and applications. The proposed antenna modal consisting of a sepal type of tapered slot edge structure in the design The simulation of the antenna modal is carried on finite element based ANSYS HFSS electromagnetic tools a prototype of the proposed antenna is fabricated on FR4 substrate an experimentally studied the antenna parameters ZNB 20 vector network analyzer. The simulated and the measured results are having good argument each other and which gives the motivation for the applicability of the proposed antenna in the desired band communication and applications.
