© 2016 IEICE. A new approach for realizing the radiation patterns of antenna systems located on a complex platform is proposed in this paper. The proposed technique is based on the use of Characteristic Basis Functions (CBFs). The CBFs are generated by exciting a number of antenna elements, typically specified by the user, and placed at 'allowable' locations on the platform. The Characteristic Basis Function Patterns (CBFPs) are derived from the CBFs, and are used as the basis functions in the pattern space to realize the desired pattern. An novel eigenvalue problem, which is numerical considerably more efficient to solve, is developed to find the best-fit solution that maximizes the energy radiated in the desired angular range, while minimizing the undesired radiation outside of this range.
