Antenna Theory - FAQ's With Answers - 3.
This page contains basic questions and short notes on some of the keywords on antenna theory: 11) What is meant by Polarization? The polarization of the radio wave can be defined by direction in which the electric vector E is aligned during the passage of atleast one full cycle.Also polarization can also be defined the physical orientation of the radiated electromagnetic waves in space. The polarization are three types. They are Elliptical polarization ,circular polarization and linear polarization. 12) What is meant by front to back ratio? It is defined as the ratio of the power radiated in desired direction to the power radiated in the opposite direction. i.e FBR = Power radiated in desired direction / power radiated in the opposite direction. 13) Define antenna efficiency? The efficiency of an antenna is defined as the ratio of power radiated to the total input power supplied to the antenna. Antenna efficiency = Power radiated / Total input Power 14) What is radi...
