The results of the desired antenna were simulated through extensive simulations performed in CST Microwave Studio®.

Moreover, ISOLA has significantly good electrical and nonelectrical properties as compared with other substrate materials. We have chosen a unique substrate material to develop our novel Antipodal Vivaldi Antenna because most research has been done on commonly used materials like FR4, RT Duroid, etc. We have designed and fabricated the improved structure of Antipodal Vivaldi Antenna with the help of new dielectric substrate ASTRA®MT77 material. This paper introduces an improved shape of Antipodal Vivaldi Antenna from the normal schematic structure which yields a high radiation gain.
