This paper analyses the mathematical design of a linear antenna array in overcoming the problem of interfering signal near to the user signal. A mathematical modelling of modified version of Schelkunoff polynomial method with Particle Swarm Optimization has been presented. The radial displacement and phase on Schelkunoff unit circle are fixed for maintaining the direction of user and interferer. Reduction of sidelobe level constraint is done by searching the best location of phases. Parameters like sidelobe level and directivity have been considered in showing the usefulness of this technique. Effectiveness and limitations of placing nulls near to the main beam have been shown by relevant examples through variation of interferer positioning.
