ANT210 - Introduction to Phased Arrays

This is an introductory course on phased array antennas. After a short review, the course describes first the simplest array, a two-element array of isotropic radiators. Then goes on to describe linear, planar, and conformal arrays. Some concepts such as sine space patterns and grating lobes are introduced. This course is intended to be a foundational course for future courses on the topic.

The course outline is as follows:
