| Abstract: |
| Objective To reduce calculation time for transient thermal and flow simulation of the active phased array antenna in accordance with the certain calculation accuracy. Methods Taguchi method was used to analyze the relevant parameters of the device position, T/R component size and other parameters in a millimeter-wave T/R component. ANOVA and factor effect analysis were adopted to indicate several parameters affecting the calculation accuracy of the simplified model and give the parameter range that can guarantee certain accuracy. Results The method presented was used to simulate and compare component and antenna array. The experimental results show that the error of the measured results of the individual component and the simulation analysis result of the individual components was less than 11%; the detailed modeling of T/R components and The maximum total error of the antenna array modeled by the simplified T/R component was 5.1 ℃ and the minimum error was 1.2 ℃. Conclusion Under the premise of W/D<0.8, the overall modeling of the chip in the component is simplified, and the accuracy of the simulation calculation can satisfy the engineering design requirements regardless of whether the single component or the antenna array is calculated. |
