Optimization of short wave ultra-wide band transmitting active antenna arrays of spatial wave

Keywords:

V.A. Nikolaev


To reduce material costs in the construction of ultra-wideband (5 – 30 МHz) transmitting antennas entire operating frequency range is divided into several sub-bands. In each of the sub-bands uses its own array. To select the optimal number of subranges minimized objective function is constructed using indicators of the quality of the antenna. Of the optimization results that the coefficient of overlap of one sub-band should not exceed 1.6.
