Recent recorded grades — Spring 2018: 3.64 GPA, 85.7% A/AB (n=7 letter grades); Spring 2023: 3.75 GPA, 80.0% A/AB (n=10 letter grades); Spring 2025: 3.83 GPA, 88.9% A/AB (n=9 letter grades).

What you’ll be able to do

  • Perform wireless system analysis, including link budget calculation for wireless communications and radar systems

  • Use Maxwell’s equations to solve basic radiation problems from electric and magnetic current distributions in space

  • Analyze and design basic types of wire antennas, including dipole and loop antennas, and aperture antennas, including horn, reflector, patch, slot, lens, and reflectarray antennas

  • Analyze and design basic types of antenna arrays, including linear and planar arrays

  • Synthesize antennas and antenna arrays to achieve a given desired radiation pattern in the far field

  • Demonstrate a fundamental understanding of antenna measurement techniques including common techniques used to measure the radiation pattern, gain, directivity, polarization, and bandwidth of an antenna under test

  • Determine a suitable antenna to use for a given application from the system level performance metrics desired including, bandwidth, gain, radiation pattern, frequency of operation, etc.

About this rating

Raw average: 5.00/5 from 2 quality ratings. The adjusted rating blends this with the UW review average (3.66/5), weighted as 20 additional ratings. Smaller samples stay closer to that average. Each captured review is counted once in the prior; this does not correct who chooses to leave a review.
