Course Description

Introduction to the fundamentals of radiation, antenna theory and antenna array design. Design considerations for wire, apeture, reflector and printed circuit antennas.

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; 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 developments and future technology advances in antenna engineering
  4. Become mindful of some nonantenna engineering aspects (manufacturability, reliability, consumer demand, constraints in materials) that influence future technology advances and contributions in research and industry

Relationship to Student Outcomes

ECE 484 contributes directly to the following specific electrical and computer engineering student outcomes of the ECE department:

  • Ability to apply knowledge of mathematics, science and engineering (high)
  • Ability to design a system, component or process to meet desired needs within realistic constraints, such as economic, environmental, social, political, ethical, health and safety, manufacturability and sustainability (medium)
  • Ability to identify, formulate and solve engineering problems (high)
  • Ability to use the techniques, skills and modern engineering tools necessary for engineering practice (high)
