Abstract

Always antenna structures with low sidelobe levels are a main goal during antenna design. In this paper, a new method for reduction of radiation patter sidelobe level in phased array antenna with uniform and non-uniform weighting is presented. In this method, by change of array elements weight or adding several elements, such as SLC technique, the pattern with low side lobe level can be achieved.According to the design, in an array with uniform weighting value of SLL in third sidelobe to next more than -10 dB can be reduced so that main beam-width changes less than %3 and variations of gain is negligible.Since in applications use non-uniform weighting so, here a new method for sidelobe level reduction in phased array antennas radiation pattern by Taylor weighting is presented. In this method, by use of uniform weighting results, the weight vector of array modify so that sidelobe reduction in resultant pattern is perceptible. In this method, the value of SLL in third sidelobe to next, ratio to primary Taylor weighting can be reduced so that main beam-width approximately %1 to %2 changes and variation of array gain is negligible. Since in phased array antennas, location of main-lobe can be set electronically by applied proper phase in arbitrary angle, performance of this method in pattern scanning is considered and shown in both way that this method is independent from main-lobe location.
