摘要

遗传规划(GP)用于设计具有新拓扑结构的天线阵列，从而提高天线的性能。利用遗传算法对共面波导连续横截(CPW-CTS)天线的三个单元进行了合成和优化。这些天线单元被串联起来，形成一个3单元的频率扫描线性阵列。用于设计CPW-CTS元件的适应度函数考虑了阻抗带宽、辐射方向图、交叉极化和透射系数。仿真结果得到了实验验证。GP设计的CPW-CTS天线阵列能够实现传统CPW-CTS阵列设计的近4倍带宽。与已发表的CPW-CTS天线阵列设计相比，GP设计的阵列保持了阵列的增益。

Genetic Programming for Coplanar Waveguide Continuous Transverse Stub Antenna Array Design

Genetic programming (GP) is developed to design an antenna array with new topologies resulting in improved performance. Three elements of a coplanar waveguide continuous transverse stub (CPW-CTS) antenna are synthesized and optimized by GP. These antenna elements are placed in series to create a 3-element frequency scanning linear array. The fitness function used to design the CPW-CTS elements accounts for impedance bandwidth, radiation pattern, cross polarization, and transmission coefficient. Simulation results are verified experimentally. The GP designed CPW-CTS antenna array was able to achieve nearly 4 times the bandwidth of a conventional CPW-CTS array design. The GP designed array maintains the array's gain when compared with the published CPW-CTS antenna array design.
