- ECE 3025 [min C]
- Catalog Description
- Concepts of electromagnetic fields as applied to microwave circuit design and antenna radiation.
- Pozar, Microwave Engineering (4th edition), Wiley, 2011. ISBN 0470631554, ISBN 978-0470631553 (required)
- Course Objectives - As part of this course, students:
- develop an understanding of the fundamental concepts associated with electromagnetic fields and the guiding and radiation of electromagnetic waves
- apply basic electromagnetic concepts to the design of microwave circuits, resonators, and antenna systems [a,c,k]
- Course Outcomes - Upon successful completion of this course, students should be able to:
- understand meaning and use of fundamental transmission line concepts: traveling and standing waves, wavelength, characteristic impedance, attenuation.
- design common transmission lines (coaxial, microstrip, stripline) to achieve a given characteristic impedance.
- understand the Smith chart (generalized reflection coefficient plane) and its use for fundamental transmission line calculations.
- design simple matching networks using lumped elements, quarter-wave sections, and stub tuners.
- understand basic principles associated with waveguide: modes (TEM, TE, TEM), cutoff frequency, guide wavelength, velocities.
- understand the concept of resonance and quality factor (Q) for lumped element circuits, transmission line sections, and metallic cavities.
- be familiar with the scattering matrix representation for microwave devices and the special properties that result for lossless and reciprocal devices
- understand the operation of simple power dividers and 4-port hybrids.
- design low pass, band pass, and high pass filters using the insertion loss method.
- understand the basic concepts associated with antenna performance, such as, field pattern, directivity, beamwidth, gain, radiation resistance.
- understand the relationship between transmission and reception for a single antenna and link calculations for two antennas (Friis formula).
