The bandwidth and resonant frequency of the flexible electrically small antenna are easily affected by deformation. In this paper, we propose an ANN-assisted yield optimization method to design a flexible electrically small antenna with stable center frequency and bandwidth. When the antenna optimized through the proposed method bends along the x or y axis with a bending radius between 70mm and 110mm, respectively, the center frequency offset, remains stable within a range of 6.3MHz (slightly over 0.5% of the target offset of 6MHz). Furthermore, the bandwidth of the antenna in the bent state approach 95.7% of the target bandwidth of 7MHz in the planar state.
