Dive into the fundamentals of radio frequency engineering for antennas in this introductory class led by Karen Rucker. Explore key concepts including electromagnetic waves, impedance matching, polarization, gain, and frequency bands. Begin with a definition of antennas, then progress through Maxwell's equations and the nature of electromagnetic waves. Examine polarization and gain before delving into radiation patterns and VSWR. Conclude with an overview of impedance matching and various frequency bands. Perfect for those looking to build a solid foundation in antenna basics, this 41-minute session serves as the first installment in the HackadayU Introduction to Antenna Basics course.
