Organized into three parts, each of which is important to the subject of electrically small antennas, Part One of Electrically Small, Superdirective, and Superconducting Antennas covers the principles of good electrically small antennas, the fundamental limitations that apply, and design data for the few basic types, the antenna designs that are based on good physics yet are poor performers, and antennas whose physics are poor and whose performances are unacceptable. Part Two provides a historical review of superdirectivity, along with a treatment of apertures and arrays. Part Three covers HTS antennas and matching networks, as well as provides a brief review of superconductors for antenna engineers.
