Some antennas are rated in comparison to dipole antennas. This is denoted by the suffix dBd, short for decibels over a dipole antenna. Hence, dipole antennas have a gain of 0 dBd ( 2.14 dBi). Note that the majority of documentation refers to dipole antennas as having a gain of 2.2 dBi. The actual figure is 2.14 dBi, but it is often rounded up.

Antennas that excite an electrical field are referred to as electrical antennas; antennas exciting a magnetic field are called magnetic antennas correspondingly. The oscillating electrical or magnetic field generates an electromagnetic wave that propagates with the velocity of light c. The speed of light in free space c0 is 300000 km/s. If the .
