Students log into secured D2L site for more course information.
Specific Course Information:
2021-2022 Catalog Data: Introduction to the fundamentals of radiation, antenna theory and antenna array design. Design considerations for wire, aperture, reflector and printed circuit antennas.
Specific Goals for the Course:
Outcomes of Instruction: By the end of this course the student will be able to:
- 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 well beyond the extent of the semester-long class.
- Have 10 or more hours of hands-on experience in antenna engineering (engineering, design, analysis) EDA tools. This experience will be demonstrated in homework assignments and a design project. The experience is often valuable skills to put on resumes.
- Be exposed to the historical aspects that relate to the current state of the art and future technology advances in antenna engineering.
- 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.
