13.1.4 Antenna Polarity 

Antenna polarization

 refers to the direction in which the electromagnetic field lines point 

as energy radiates away from the antenna. In general, the polarization is elliptical. The 
simplest and most common form of this elliptical polarization is a straight line, or 

linear 

polarization

.  

An antenna only receives the portion of the transmitted power that has the same 
polarization as the receiving antenna polarization. For example: 

  If the transmitting antenna polarization is in the vertical direction (vertical 

polarization), and the receiving antenna also has vertical polarization, the maximum 
amount of power possible is received. 

  On the other hand, if the transmit antenna has vertical polarization and the receiving 

antenna has horizontal polarization, no power should be received. If the two 
antennas have linear polarizations oriented at 45° to each other, only half of the 
possible maximum power is received.
