采用协方差矩阵自适应进化策略（CMA-ES）得到了矩形介质谐振器天线的单双模设计新公式。与之前的双模公式相比，新的双模公式的优点在于它允许输入特定尺寸比的DRA。此外，它比以前的更简单，但更准确。为了验证公式的正确性，设计并制作了4个不同尺寸比的双频矩形dra，测量的谐振频率与设计频率吻合较好。模拟和测量了其中一种双频dra的反射系数、辐射方向图和天线增益。
New single-/dual-mode design formulas of the rectangular dielectric resonator antennas (DRAs) are obtained using the covariance matrix adaptation evolutionary strategy (CMA-ES). The new dual-mode formula has an advantage over the previous one in that it allows an input of a specified dimension ratio of the DRA. Also, it is simpler but more accurate than the previous one. To validate our formulas, four dual-band rectangular DRAs of different dimension ratios were designed and fabricated, and the measured resonance frequencies agree very well with the design frequencies. The reflection coefficients, radiation patterns, and antenna gains of one of the dual-band DRAs were also simulated and measured.
