Chapter 1: Introduction. In this chapter a brief history of antennas is presented. The source of electromagnetic radiation is discussed and the mechanism by which radiated fields emerge from an antenna is explained. A brief overview of the antenna types dis- cussed in this book is presented.

1. Definition of the Antenna and Wave-Motion The radio antenna may be defined as the interface between a circuit in which electrical power is constrained to follow conducting paths, and electromagnetic radiation travelling freely through space. The antenna may convert power in the circuit into radiated energy or vice versa, forming either

To obtain a closed form solution, antenna geometry must be described by an orthogonal curvilinear system. If not possible, the following methods are applied: Geometrical Theory of Diffraction (GTD): Antenna system is many wavelengths. GO’s disadvantage is overcome by including diffraction mechanism (high frequency).
