Analysis of Antenna Manufacturing Methods: Addressing Challenges in 3D Printing

This study discusses the design and fabrication process of a bowtie antenna using a traditional milling method and a 3D printing method. The various parameters related to the manufacturing process are discussed, and their effect on the design process is highlighted. Both a milled antenna and a fully 3D printed antenna were fabricated and the design and manufacturing process of the two antennas was compared. This paper particularly focuses on the intricacies of antenna design through 3D printing. The objective of the research is to compare and contrast the two fabrication processes and highlight the challenges associated particularly with using 3D printing technology. The improvement of these shortcomings helps to mature 3D printing technology and work toward improvements for future electromagnetic applications.
