This paper presents an Antipodal Vivaldi Antenna (AVA) design, focusing on its constructional aspects. The main features analysed are the connector attachment structure and introduction of a polytetrafluoroethylene (PTFE) part that supports antenna laminate. Issues related to dielectric penetration by milling tools also addressed. proposed AVA was manufactured through low-cost prototyping proce...

In order to expand the applications of traditional Vivaldi antenna by addressing low gain antenna, this paper combines phase distribution aperture based on analysis transmission characteristics a dielectric unit utilizing advantages artificial electromagnetic material. A more reasonable method loading lens is proposed and utilized in combination with edge grooving. comparison results shows that...
