This course is also offered through Engineering-LAS Online Learning. Off-campus students can take EE517 without the laboratory as EE510XE with 3 credits.
Instructor: Jiming Song
Office Hours: Coover 2130, Monday and Wednesday, 1-2pm.
Textbook, references, and Notes
Homework: Homework assignments will be given Wednesday and are due exactly a week later for on-campus students. The off-campus students have 5 more days. The last homework assignment and the second project are due in the last class (dead week)

Final Grade Breakdown for EE417 (there are extra projects for EE517/EE510 students):
(Off-campus students should find a proctor and work with their potential proctor to fill out the approval form)
1. Define the following terms: isotropic antenna, radiation intensity, gain, directivity, radiation efficiency, effective area, polarization, radiation resistance, bandwidth, radiation pattern, beamwidth, sidelobe level, aperture efficiency, and primary and secondary patterns;
2. Given the gain of an antenna and the power it accepts from a source, calculate the radiated power density and the field intensities at a given distance and assess potential hazards from radiation exposure. Derive the Friis transmission formula and the radar formula;
3. Define far field and determine the minimum distance for far-field conditions;
4. Given a uniform linear array of antennas, calculate the progressive phase shift of excitation to produce a main beam in a desired direction. State the principle of pattern multiplication. Use it to find the radiation pattern of an array of identical elements;
5. Describe qualitatively the way in which equivalent sources are used to determine the radiating characteristics of aperture-type antennas;
6. Given a receiving system with individual gains and noise temperatures or noise figures, estimate the overall noise temperature and noise power referred to the system input.
7. Define Fresnel zone clearance. Explain why a 4/3-earth-radius is used for profiling. Describe qualitatively the effect of the earth's ionosphere;
8. Explain qualitatively the operation of a wire antenna, a Yagi-Uda array, a microstrip antenna, and a log-periodic dipole array, and discuss their advantages and disadvantages;
9. Use basic laboratory equipment to measure gains and radiation patterns of antennas;
10. Use a moment-method numerical analysis program to model and analyze the fields from an antenna system.
Iowa State University is committed to assuring that all educational activities are free from discrimination and harassment based on disability status. All students requesting accommodations are required to meet with staff in Student Disability Resources (SDR) to establish eligibility. A Student Academic Accommodation Request (SAAR) form will be provided to eligible students. The provision of reasonable accommodations in this course will be arranged after timely delivery of the SAAR form to the instructor. Students are encouraged to deliver completed SAAR forms as early in the semester as possible. SDR, a unit in the Dean of Students Office, is located in room 1076, Student Services Building or online at www.dso.iastate.edu/dr/.
