Project of antenna arrays with random parameters

Abstract

This paper presents a new way of projecting linear arrays structures using random excitation coefficients and random spacing between sensors. The results obtained show that these configurations can produce good radiation patterns in terms of side lobes level and other project specifications. Depending upon chosen parameters the radiation pattern can be optimized as compared to the one obtained using binomial coefficients. It can be as good as the patterns obtained using the Dolph-Tschebyscheff algorithm. This method can be used in order to get a smoother radiation pattern and can be useful to control the radiation pattern in response to user mobility. Another advantage is related to the numerical processing involved in the computation of excitation coefficients. They are chosen randomly from a convenient set, while in the other cases they are computed in real time and depend upon antenna dimensions, a task which can be computer intensive.
