Measurements. Antennas in Wireless Systems. Antenna Synthesis, Waveguide slot arrays. Microstrip antennas. Numberical techniques. Moment method analysis of wire antennas. Geometrical theory of diffraction, finite-difference time-domain techniques.

What is the reason for this course?

The course sequence ECE 6115, 6116 provides intensive education in antenna design. Antennas are essential to communications and remote sensing. In particular, today’s explosion in wireless communications has increased the demand for radio frequency engineers who can design hardware in sophisticated applications. Antennas are an integral part of any wireless system.

Typically offered: Spring. Program Area: Electromagnetics.

Prerequisites: 5105.

Why are these prerequisites or corequisites required?

Understanding basic introductory graduate electromagnetic wave theory as covered in 5105 is necessary for these courses.
