Radiation and Antennas

Antenna is a radiator and sensor of EM waves. It is also a transducer and impedance matching device. It can be designed to direct EM energy in desired directions and suppress it in unwanted directions.

The main aim of this chapter is to provide the fundamentals of antennas. They include:

  • antenna definition, functions, properties and parameters
  • basic antenna elements
  • radiation mechanism, radiated power and radiation resistance of current elements, dipoles and monopoles
  • directional characteristics of basic elements
  • solved problems, points/formulae to remember, objective and multiple choice questions and exercise problems.
