EE 521 Microwave Engineering
- 1994-95 Catalog Data: 3 credits
- Techniques for microwave measurements and communication system design,
including transmission lines, waveguides, antennas and components. Corequisites
EE 415 and EE 471L.
Same as EE 471 with differentiated assignments for graduate students.
- Textbooks:
- Microwave Engineering, David M. Pozar, Addison Wesley, 1990.
- Reference:
- None.
- Coordinator:
- Gary Hancock, Professor of Electrical and Computer Engineering.
- Goals:
- To introduce students to microwave systems, components, devices and
techniques. The wave propagation fundamentals studied in the Electromagnetics
II course will be applied to wave guiding systems such as transmission lines and
waveguides. Applications are stressed. Homework assignments and class projects
include tasks in which engineering design trade-offs must be made. The course
culminates in a final project which includes design, analysis, fabrication and
test of a microwave filter.
- Prerequisites by topic:
- Vectors
- Phasors
- Maxwell's equations
- Topics:
- Review of Maxwell's equations including general plane wave and
propagation in anisotropic media. (3 classes)
- Transmission line theory: Practical circuit models, Smith charts, lossy
lines and slotted line measurements. (5 classes)
- Waveguides: Solution of the wave equation, mode excitation, design of
waveguide-to-coax adaptors, attenuation calculations and power handling
capability. (5 classes)
- Microwave network analysis: Scattering matrices and mulitport analysis
techniques. (5 classes)
- Impedance Matching: Design of tuners and general matching networks
including lumped elements, stubs and transmission line sections. (3 classes)
- Components: Theory of operation, practical design and implementation
of power dividers, directional couplers and hybrids as well as system
applications of these devices. (5 classes)
- Filters: Filter design and implementation. (5 classes)
- Active Circuits: Detectors, mixers, PIN diodes, and noise including
practical design of PIN attenuators, modulators and limiters. (6 classes)
- Microwave Systems: Receiver and system noise figure calculations as
well as link analysis. Engineering design formulas for antennas as well as
end-to-end microwave system analysis. (5 classes)
- Tests. (2 classes)
- Project:
- In addition to homework assignments and in-class exams, this course
includes a semester design project. The project involves the design (to
specifications), analysis, fabrication and test of a microwave filter. The
microwave measurements , which must be completed to determine if the
component meets specifications, are performed during the accompanying EE 471L laboratory periods.
