通过双蚁群算法对微带天线的贴片以及底面进行开窗设计,以实现微带天线的多频工作性能。算法采用双蚁群二次优化的方法,并应用16进制编码,使其可以在有限的计算机硬件条件和较短的计算时间内,得到具有较优天线性能的微带天线,并成功设计出一款可在WiMAX(2.5-2.7GHz,3.4-3.69GHz,5.25-5.85GHz)三频段内工作的多频微带天线。最后制作了天线实物,其测试数据和仿真数据较为接近,验证了应用双蚁群算法设计多频天线的可行性。
The double ant colony algorithm is used to design the window of the patch and the bottom of the microstrip antenna so as to realize the multi-frequency working performance of the microstrip antenna. The algorithm uses the double ant colony optimization method, and uses hexadecimal encoding to make it possible to obtain the microstrip antenna with better antenna performance under limited computer hardware conditions and short computation time, and successfully design A multi-band microstrip antenna that operates within the tri-band WiMAX (2.5-2.7GHz, 3.4-3.69GHz, 5.25-5.85GHz). Finally, the antenna is made in-kind, and the test data and simulation data are close to each other, which verifies the feasibility of designing a multi-frequency antenna by using double-ant colony algorithm.
