A New Approach for Synthesizing Both the Radiation and Scattering Patterns of Linear Dipole Antenna Array

A new approach for simultaneously synthesizing the radiation and scattering patterns of linear dipole antenna array is investigated. In this method, the analytical formulas of the radiation field and scattered field of linear dipole antenna array are derived in terms of self-impedance, mutual-impedance and terminal load impedance. So the mutual coupling effects between the elements can be taken into account. Based on these two formulas, the desired radiation and scattering patterns of the array can be synthesized simultaneously by optimizing element placement. As an example, the proposed method is used in designing a linear dipole antenna array with low radiation and scattered sidelobe level. Numerical results validating the accuracy and great effectiveness of the method are also provided in this paper.
