A characteristic mode analysis of an antenna array consisting of N elements is first carried out to identify its different radiating modes. Based on these characteristic modes, the DE algorithm is then employed to seek the optimal mode excitation coefficients according to design specifications. Several circular antenna arrays are successfully synthesized according to main beam direction and maximum sidelobe level. The benefits brought by the theory of CM are illustrated in terms of the quality of the optimal design and the computational complexity. © 2012 IEEE.||Source Title:||IEEE Antennas and Propagation Society, AP-S International Symposium (Digest)||URI:||http://scholarbank.nus.edu.sg/handle/10635/116771||ISBN:||9781467304627||ISSN:||15223965||DOI:||10.1109/APS.2012.6348999|
