Technology has advanced to such a degree over the last decade that it has been almost impossible to find up-to-date coverage of antennas. 

Antenna Handbook, edited by two of the world's most distinguished antenna speciallists, presents the most advanced antenna theory and designs and demonstrates their application in a wide variety of technical fields. 

They offer a staggering amount of in-depth data and analysis on a wide range of topics, supported by formulas, curves, and results, as well as derivations.
