Aiming at the singularity and slow convergence problem of cylindrically conformal microstrip antenna with cylindrical stratified and vector-wise Green’s function, a method of effectively analyzing and calculating the probe-fed cylindrical conformal microstrip antenna is proposed in this paper. First of all, a sub-region calculation method is proposed to overcome the shortcomings of singularity and slow convergence encountered in the calculation process. Then, using the metal strip equivalent probe model, the probe feed cylindrical conformal microstrip antenna was theoretically analyzed by RWG basis function and moment method. Finally, the validity and correctness of the proposed method are verified by simulation. The calculation of conformal antenna on cylindrical aircraft has an important theoretical value and practical significance in engineering calculation.
