Determinação do ganho de antenas pelo método da comparação utilizando sistema móvel.

Abstract

Treating of a passive structure, the antenna operates the energy contained in electromagnetic waves simply acting as a transducer, for this reason, when the project is designed, this should be implemented in order to optimize the reception and transmission aimed at reducing losses. Knowing that a real antenna has an ability to direct or focus the energy in a given direction in space (compared with an ideal antenna as reference), its position should be selected carefully, so that it is not subject to interference from the middle external. This paper will be based on the study of determination of the gain of antennas using the comparative method. In turn, these antennas may be coupled to a computer-controlled mobile system which will optimize the results.
