Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: A study on the impact of the phase errors distribution on the performances of the phased array systems has been produced using a complete behavioral model for radiation-pattern characteristics. The main purpose of the study is to demonstrate that the rms phase error is a valuable figure of merit of phased array systems but it is not sufficient to completely describe the behavior of a real system. Indeed, even the way in which the phase errors are distributed among antenna elements actually affects the performances of the phased arrays antennas. The developed model has many input parameters and it has a lot of features, such as parameter simulations with results analysis, unconventional two-dimensional color graph representation capability in order to show more clearly the results. It is also a useful tool that can be used in system and design phase of a phase shifter. The results of the study demonstrating the previous considerations have been reported.
