ELEN421 - RF/Microwave Engineering I

Course Details

Course Code: ELEN421 Course ID: 4608 Credit Hours: 3 Level: Undergraduate

This course covers the fundamental concepts of passive microwave circuit analysis and design. Topics include electromagnetic theory, propagation of electromagnetic waves in various transmission media, microwave network analysis, the Smith Chart, impedance matching & tuning, resonators, power dividers, directional couplers, and microwave filters. At the end of this course, you will have an understanding of the key concepts and components associated with passive microwave circuits. (Prerequisites: ELEN350) NOTE: This course requires the student to purchase additional materials that are not covered by the book grant. Please refer to the Course Materials section for additional details.

After completing the course, the student should be able to accomplish these Course Learning Objectives (CLOs):

  1. Explain RF & Microwave Theory
  2. Analyze transmission lines, including quarter wave transformers & impedance mismatches
  3. Explain the capabilities of microwave power dividers, directional couplers, and microwave filters
  4. Analyze the performance of individual RF/Microwave components
  5. Analyze an RF/Microwave network
  6. Design an RF circuit to solve a specific problem or requirement using common RF design tools
  7. Prepare effective communication material using technical data

Instructor announcements: Weekly announcements will appear on Monday of each week in the online classroom. They will also be e-mailed to each student. The announcements discuss the assignments and any other pertinent information for the week.

This is an upper level course. All students’ work is to be presented as such in terms of quality and content. The grading system is based on eight forums (20%), eleven homework assignments (40%), and four tests 40%).

Reading Assignments: Refer to the Course Outline section of this syllabus for the weekly reading assignments

Week 1 Introductions: Within 7 days of course start, you must log into the classroom and introduce yourself to the class. Your response is due by Sunday of Week 1. Your response must be a minimum of 250 words (a requirement) and should include the information listed in the Forum instructions.

Weekly Forums: There are two kinds of discussion forums in this course. The first are for course-specific topics chosen by the instructor. These are graded assessments. The second are free-form forums for questions and topics generated by the students. Students are fee to post any relevant question in the free-form forums but should avoid asking questions about specific gradable test questions. If there are questions about specific test questions, find a similar problem in the book and ask a question on that problem or concept instead. Asking questions about specific test questions creates an unfair advantage and defeats the purpose of the assessment tool.

Exams: There are four exams, each worth 10% of your final grade. It is an open book, open note exam. It is administered without a proctor. Students must complete the exams by the end of the week indicated in the schedule.

Lab Exercises: Where specified, homework assignments may take the form of virtual lab exercises completed in a computer simulation environment. Because modern RF/microwave engineering is highly dependent on computer simulation, participation in these assignments is mandatory. If you fail to participate in the lab-based assignments in a meaningful way, you will not pass the course.
