3D Printing Antennas and Other Dark Arts

Antenna design is commonly regarded as one of the hardest specialties of RF engineering, and frequently called "black magic." But if you're not scared of learning a little magic - and you don't have access to six-figure antenna design software - what are some cool projects you could do as an introduction to designing and building your own antennas? What makes an antenna "good?" Karen Rucker (callsign KG5GAK) will give an introduction to hobbyist antennas designed for even entry-level ham radio operators, or just those that have an interest.
