Antenna is a structure which serves as a transition between wave propagating in free space, and the fluctuating voltages in the circuit to which it is connected. An antenna either receives energy from an electromagnetic field or radiates electromagnetic waves produced by a high frequency generator. This section deals specifically with antennae used in radar installations.

Learning objectives:
The learning objectives serve as a preview of the information you are expected to learn in the chapter. This chapter provides the basis for understanding the specific radar antennae. Upon completion of this chapter, the student will be able to:
- describe antenna directivity and power gain characteristics;
- describe the focusing action of a basic parabolic antenna;
- describe the basic radiation patterns of the most common parabolic reflectors;
- describe the basic characteristics of horn radiators;
- describe the monopulse antennae concept.
