ECE 323: Microwave Engineering

ECE 323: Microwave Engineering
SPRING SEMESTER 2018
Department of Electronics and Electrical Communications Engineering

 Microwave engineering is growing in importance with each passing year. It has application to the wireless industry and to high density electronic packaging for computer systems with fast clock speeds. Some common applications of passive microwave circuits include communication systems (e.g., satellite-to-ground link), mobile phones and wireless local-area-network, radar, navigation and guidance systems (e.g., GPS), antennas, radio astronomy, electronic warfare, remote sensing, and biomedical devices.

                                            Problem Sets

Problem sets are assigned approximately every week. Much of the material in this course must be learned by example and practice. Many homework assignments require extensive analysis and you are therefore encouraged to start early.

Microwave Laboratory

The lab is designed to help illustrate many of the concepts from the lecture and to delve deeper into practical issues that can only be acquired through careful experimentation. Each lab experiment involves reading related to the course material, the actual lab construction and measurements, and a lap report. 
Experiments include:
  • Lab 0: Laboratory Introduction and Organization 
  • Lab 1: Measurement of Impedance and Impedance Matching
  • Lab 2: Microwave Radio Link Investigations +  Horn Antenna Investigations
  • Lab 3: Waveguide Directional Coupler
  • Lab 4: Series, Shunt and Hybrid Tee Junctions
  • Lab 5: Waveguide to Coaxial Transformers
  • Lab 6: Microwave passive components design using ADS.

               Piazza: Online Discussion Forum

This term we will use Piazza for class discussion. The system is highly catered to getting you help fast and efficiently from classmates, the TAs, and  myself.  Rather than emailing questions to the teaching staff, I encourage you to post your questions on Piazza.
