Antenna concepts

The antenna converts electromagnetic energy in a cable into electromagnetic radiated power in free space.

Various characteristics of the antenna determine "how efficient" this conversion is performed:

- To have as much energy as possible carried on as radiation in the room is of great importance, i.e. the antenna should not be capable of consuming energy itself.

- It is important that the antenna concentrates its radiated energy as efficiently as possible in the required way.

If so, either a wide coverage range or a reduced transmitting power can be achieved, until the range is exactly suiting the one required.

 

Consequently, antenna technology is simply a question of economizing on the energy.
