Noise figure of an active antenna array
DOI: 10.21293/1818-0442-2017-20-4-7-10
Abstract: The article considers the noise characteristics of an active antenna array (AA) with an arbitrary aperture field distribution. The noise figure of an active AA was defined, calculated relating to an antenna array with a random in-phase aperture amplitude distribution, and expressed in terms of common characteristics for antenna engineering. Quantitative benefits of the noise figure of the active AA in respect to the passive AA (in case of the identical directional response) are demonstrated.
Keywords: antenna array, noise figure, in-phase aperture amplitude distribution, aperture, antenna pattern
