Dipole
1. An antenna consisting of a straight conductor usually not more than a
2. Any one of a class of antennas producing a radiation pattern
Electromagnetic compatibility (EMC)
1. The capability of electronic equipment of systems to be operated within
2. EMC is the ability of equipment to function satisfactorily in its
Electromagnetic interference
Electromagnetic interference is the impairment of a wanted electromagnetic
signal by an electromagnetic disturbance
Electromagnetic wave
The radiant energy produced by the oscillation of an electric charge
characterized by oscillation of the electric and magnetic fields.
Emission
Electromagnetic energy propagated from a source by radiation or conduction.
Far Field
The region where the power flux density from an antenna approximately obeys
an inverse squares law of the distance. For a dipole this corresponds to
distances greater than l/2 where l is the wave length of the radiation.
Ground plane
1. A conducting surface or plate used as a common reference point for circuit
2. A metal sheet or plate used as a common reference point for circuit
