This is an excellent antenna text. I would say in general the heuristic explanations are very clear and a wide range of antennas are covered.



Perhaps at some points the math is glossed over just a tiny bit, and so if you're really trying to derive things along with the text, it can be a challenge to reproduce some of the results.



The introductory treatment of computational EM methods in the last few chapters is truly outstanding! I have particularly enjoyed the chapter on the method of moments -- the formulation is simplified enough so that you can code up your own toy programs. Advanced topics are mentioned as well. Very nice!
