* '''Antenna polarization'''' is direction in which electric field oscillates while it propagates through environment. It is important to match broadcasting and receiving antennas polarization: it must be same polarity. In this way the maximum signal is obtained. Wi-Fi antennas are almost always vertically polarized, while mobile antennas are either vertically polarized or cross polarized | * '''Antenna polarization'''' is direction in which electric field oscillates while it propagates through environment.

** Decibels (dB) – 10 dB means 10 times the energy relative to an isotropic antenna in the peak direction of radiation | ** Decibels (dB) – 10 dB means 10 times the energy relative to an isotropic antenna in the peak direction of radiation | ||
** dBi (decibels relative to an isotropic emitter) is the same as dB because isotropic antenna has gain of 1dB | ** dBi (decibels relative to an isotropic emitter) is the same as dB because isotropic antenna has gain of 1dB | ||
** dBd (decibels relative to a dipole antenna) – dipole gain has a gain of 2.15dBi so 10dBi antenna has gain of 7.85dBd | ** dBd (decibels relative to a dipole antenna) – dipole gain has a gain of 2.15dBi so 10dBi antenna has gain of 7.85dBd | ||
