Course Learning Outcomes:

By the end of this course, the student will:

1. Have practice with foundational aspects of antenna engineering through homework and problem analysis. The foundations are not extensive, yet the student will develop quality and critical thinking checks necessary for extended study and mastery of selected subjects in antenna engineering.
2. Have 10 or more hours of hands-on experience in antenna engineering (engineering, design, analysis) EDA tools.
3. Be exposed to the historical aspects that relate to the current state of the art and future technology advances in antenna engineering.
4. Become mindful of some non-antenna engineering aspects (manufacturability, reliability, consumer demand, constraints in materials) that influence future technology advances and contributions in research and industry.
