"Pozar's new edition of Microwave Engineering includes more material on active circuits, noise, nonlinear effects, and wireless systems. Chapters on noise and nonlinear distortion, and active devices have been added along with the coverage of noise and more material on intermodulation distortion and related nonlinear effects. On active devices, there's more updated material on bipolar junction and field effect transistors.New and updated material on wireless communications systems, including link budget, link margin, digital modulation methods, and bit error rates is also part of the new edition. Other new material includes a section on transients on transmission lines, the theory of power waves, a discussion of higher order modes and frequency effects for microstrip line, and a discussion of how to determine unloaded"
Cheng's "Field and Wave ELectromagnetics" is an excellent undergrad book to start to learn then you have Harrington's "Time Harmonic Electromagnetic Fields" and Stratton's "Electromagnetic Theory" which are both really fundamental and thorough and more high end you have Collins' "Foundation of Microwave Engineering" and "Field Theory of guided waves"
A bit more practical if you like smith charts you've and matching networks you've got Pozar's "Microwave Engineering"
and for Antenna theory you've got Stutzman and Thiele's "Antenna Theory and Design" or Kraus' "Anetnnas"
Balanis' book is good but a lot of the material in in comes from these books + Jackson and I think it makes a much better reference than a learning text.
