Antenna Directivity and Gain

Those antennas that do not radiate in all directions in an equal manner are referred to as RF antennas. Most RF antennas will tend to give more radiations to one direction more than others do.

There are factors that determine the pattern with which an antenna will radiate and these include the how the antenna has been designed, the size as well as the environment in which it stands. Antenna direction ensures that the radiated power points to the right direction. Referring to the patterns in direction and gaining in signal transmission is always normal.

The RF antenna can be visualized much easier when it comes to radiating power although there is an equivalence in the performance of the antenna in terms of reception when it has figures that are identical as well as the specifications. The RF antenna gains through the radiation of a specified ration of power. This power is then taken to the resistance of radiation found in the RF antenna. This gain can also be called a forward gain.
