Vivaldi antenna design and simulation with Bakelite substrate compared to RT duroid 5880 substrate

The main objective of this paper is to show the difference between two vivaldi antennas simulated with two different substrates, the first one is bakelite, since it is very easy to find a phenolic plate for the simplest electronics projects, this type of plate consists of one or two copper plates on the outside and a bakelite plate that separates them, However, the intention of the article is to compare this type of material so commercial with a material that has gradually made its way into the field of communications in a wide bandwidth, called RT duroid 5880 from Rogers Corporation and show the differences in relation to the gain. It is worth mentioning that this work shows the development of the antenna design using simulation software and that the development of this antenna will be adapted to contribute to later projects.
