| Abstract(in English) | Electronically steerable passive array radiator (ESPAR) antenna perform s analog aerial beamforming and has only a single-port output that can be observed. This lack of spatial information and highly nonlinear dependence of output of the antenna from adjustable reactances requires unconventional approach to the beamforming. A novel approach based on stochastic approximation theory is devoted to adaptive beamforming of ESPAR antenna as a nonlinear spatial filter by variable parameters, thus forming both beam and nulls. Our theoretic study and simulation results show that ESPAR antenna can be controlled effectively has strong potential to be used in mobile terminals and seems to be very perspective. |
