摘要
采用自适应混合差分进化(SHDE)算法对一种新型的小型超宽带改良叉形印刷天线进行了高效优化。首先，提出了一种新型的超宽带改良叉形印刷天线结构。尺寸更紧凑的天线由改进的叉形散热器和改进的地平面组成，可以覆盖非常宽的工作频带。该天线采用阶梯微带线馈电，修改后的接平面由若干矩形槽和l型短段组成。然后，使用SHDE算法确定天线的结构尺寸，在保持高效计算时间的同时优化天线的性能。优化后的天线尺寸仅为11.8 mm × 19.7 mm，在3.08 ~ 20.46 GHz范围内-10 dB反射系数带宽为147.6%。最后制作了天线样机，测量结果与仿真结果基本吻合。该天线是实现超宽带传输技术的理想选择。
Design of Novel Ultrabroadband Printed Antenna and Its Efficient Optimization Using Self-Adaptive Hybrid Differential Evolution Algorithm
A novel compact ultra-broadband-modified fork-shaped printed antenna is optimized efficiently by using a self-adaptive hybrid differential evolution (SHDE) algorithm. Firstly, a novel compact ultra-broadband-modified fork-shaped printed antenna structure is proposed. The antenna with more compact size consists of a modified fork-shaped radiator and a modified ground plane, which can cover a very wide operating frequency band. The antenna is fed by a step-shaped microstrip line, and the modified ground plane consists of some rectangular slots and an L-shaped stub. Then, the SHDE algorithm is used to determine structural dimensions of the proposed antenna, and the antenna’s performance is optimized while maintaining a cost-effective computation time. The optimized antenna with only

size covers -10 dB reflection coefficient bandwidth of 147.6% from 3.08 to 20.46 GHz. Finally, the antenna prototype is fabricated, and the measured results basically agree with the simulated ones. The proposed antenna can be viewed as an excellent candidate for realizing ultrabroadband transmission technology.
