Aev antena log periodica
WebAug 24, 2024 · A fixed surveillance system requires a DF antenna in the form of an array consisting of multiple antenna elements that are arranged in a circular formation. The antenna elements can be among several antenna types such as dipole antennas, monopole antennas, bi-conical antennas, log-periodic antennas, and Vivaldi antennas. WebThe design procedure of the log-periodic dipole (LPD) antennas is discussed. The results of the calculations carried out by the use of the more recent and accurate methods of the analysis for the arrays of unequal dipoles, are compared with those already available in the literature. The calculations refer to the gain of LPD antenna as a ...
