Preface and Text Organization
The first edition of this book and the subsequent work of coauthors resulted in MATLAB® Antenna Toolbox™ – a dedicated learning and research software tool for major antenna and array types. Internally, the toolbox uses the Method of Moments (the method of integral equation) for modeling metal and metal‐dielectric antennas. Rao–Wilton–Glisson basis functions on triangular facets are used for the metal parts and edge basis functions on tetrahedra are used for the dielectric parts. Accurate semi‐analytical calculation of near‐field interactions between neighbors facets and tetrahedra assures good solution accuracy.
The Antenna Toolbox has a relatively flexible 2.5D CAD geometry generator and it has an option to import an arbitrary surface antenna or an antenna platform mesh. In addition to multiple programmatic examples, it features over 60 different predesigned antenna configurations grouped by various families such as patch antennas, monopoles, dipoles, spirals, etc. and continues to grow.
In contrast to the first edition devoted to the development of numerical modeling, this second edition is structured differently. It is presented as a succinct yet self‐contained introduction to basic antenna modeling and design with an emphasis on the antenna modeling with the already available MATLAB® Antenna Toolbox. Special attention is paid to small antennas where the Method of Moments remains the most accurate modeling tool. The present text has been used for a one‐semester graduate or a senior‐level undergraduate course for EE/ECE majors and other interested students. It can also be used for an independent study.
The text covers major antenna and array types, and concepts, along with the necessary theoretical background. The text also includes a number of practical antenna/array design examples performed by the authors. Wherever possible, we refer to more comprehensive and fundamental antenna books by C. A. Balanis, W. L. Stutzman, G. A. Thiele, R. C. Hansen, T. Milligan, and the others.
The text organization is shown in Table 1. It includes printed matter, MATLAB® Antenna Toolbox video laboratories, video tutorials, and video lectures, and is targeting either mixed or online material delivery. For running laboratories, MATLAB® 2018 or newer is required with Antenna Toolbox and RF Toolbox installed.
TABLE 1 Organization of printed matter, video laboratories, tutorials, and video lectures. The text content has been tentatively divided into 12 lectures; other arrangements are possible, indeed. Video laboratories (shadowed) teach how to use the Antenna Toolbox.

One ongoing extension of the Antenna Toolbox is the utilization of the Fast Multipole Method (FMM) developed by the group of Dr. Leslie Greengard and the others. It is intended to enable modeling large antenna reflectors, antennas on large platforms (airplanes and cars), and large antennas arrays.
The online materials contain a suite of open‐source MATLAB® scripts along with the supporting supplement, which demonstrate how to implement this approach and how to apply it to antenna reflectors and scatterers of large compared to the wavelength sizes.
We thank Dr. Angelo Puzella of Raytheon Technologies for numerous constructive comments and suggestions.
