In a receiving antenna, the gain describes how well the antenna converts radio waves arriving from a specified direction into electrical power. When no direction is specified, gain is understood to refer to the peak value of the gain, the gain in the direction of the antenna's main lobe. Visa mer In electromagnetics, an antenna's gain is a key performance parameter which combines the antenna's directivity and radiation efficiency. The term power gain has been deprecated by IEEE. In a transmitting antenna, … Visa mer Gain is a unitless measure that combines an antenna's radiation efficiency $${\displaystyle \eta }$$ and directivity D: $${\displaystyle G=\eta D}$$ Visa mer Published numbers for antenna gain are almost always expressed in decibels (dB), a logarithmic scale. From the gain factor G, one finds the gain in decibels as: $${\displaystyle G_{\text{dBi}}=10\log _{10}\left(G\right).}$$ Therefore, an … Visa mer Realized gain differs from gain in that it is "reduced by its impedance mismatch factor." This mismatch induces losses above the dissipative losses described above; therefore, realized gain will always be less than gain. Gain may be expressed as absolute gain if … Visa mer The radiation efficiency $${\displaystyle \eta }$$ of an antenna is "The ratio of the total power radiated by an antenna to the net power accepted by the antenna from the connected … Visa mer First example Suppose a lossless antenna has a radiation pattern given by: $${\displaystyle U=B_{0}\,\sin ^{3}(\theta ).}$$ Let us find the gain of such an antenna.
