Analysis of Cylindrically Conformal Dipole Array using Periodic Stratified Media Green's Function

Conformal antenna array becomes more popular on aircraft owing to significant improvement of aerodynamic and stealth performance. However, due to the interaction of its platform, full-wave analysis discretizes the platform and hence requires lots of computing resource. In this paper, an efficient method for conformal dipole array with cylindrically stratified media structure is developed. The cylindrically periodical stratified media Green's Functions (CPSMGFs) is derived and applied in the method of moments (MoM). Input impedance of the array element can be efficiently analyzed. According the comparison of the results with FEKO, the proposed method is proved feasible, and the computational time reduces by two magnitudes as an example.
