Radar Antenna Engineering. 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.
