Abstract

Large antennas and microwave antennas, which form the subject of the remaining chapters of this book, are characterized by the property that their useful dimensions are very large compared with the wavelength involved. The word ‘large’ refers to the physical dimensions of the antenna (radio telescopes, for example) compared with which the wavelengths involved are so small (centimetres or millimetres) that very specific technologies may be involved. In this way, a glass lens may be considered as a large antenna whereas a radio transmitting tower may be considered ‘small’ in comparison with the wavelengths it transmits.
