Reading Assignments for Apr. 14–18 (4/12/2025)

• M: Sections 11.6, and 11.7
• W: Sections 2.1 through 2.8, and skim the supplemental readings "Radiation Power and Directivity of Antennas," "Radiation Resistance, Efficiency, and Gain of Antennas," and "Loss Resistance Calculations for Arbitrary Current Distributions"
• F: Section 2.11 and Sections 9-9 through the beginning of 9-11 of the ECEG 390 textbook by Ulaby & Ravaioli, 7th or 8th edition

Skim Sections 2.1 through 2.7 if you are taking ECEG 390 this semester.

Consider also reading (or re-reading) Sections 9-0 through 9-2 of the ECEG 390 textbook. These sections in Ulaby cover largely the same material (fundamentals of radiation and antenna theory) as the early sections in Ellingson's Chapter 2 but from a slightly different point of view. If one author is not clear on some topics, hopefully the other one is. I recommend that you read both treatments if you have a copy of Ulaby's book.

All of the supplemental readings are available at the course Moodle site.
