摘要
通过新的粒子群优化(PSO)实现，重新审视和优化了用于WLAN应用的微带E形贴片的创新4元素阵列拓扑。该优化器能够减少成本函数评估的数量，因为所有评估的天线配置和相应的成本函数值都被保存。在粒子群优化过程中，采用基于矩量法的全波求解器对粒子的适应度进行评估。为了达到最优的性能，使用s参数和数组增益来构造所使用的代价函数。工作频率范围为3.4 ~ 3.8 GHz，阵列增益大于13db。主波束方向垂直于地平面。最后利用CST EM Studio对全局最佳候选天线结构进行验证。
Optimized design of a compact low-cost 4 element microstrip antenna array for WLAN
An innovative 4 element array topology of microstrip E shaped patches for use in WLAN applications is revisited and optimized by a novel Particle Swarm Optimization (PSO) implementation. This optimiser is capable to operate with a reduced number of cost function evaluations, since all evaluated antenna configurations and corresponding cost function values are saved. During the PSO optimization process, the fitness of the particle is evaluated by a full wave solver based on the moment of method. The used cost functions are constructed using s-parameters and the array gain in order to achieve the optimal performance. The operating frequency range is from 3.4 to 3.8 GHz and the gain of the array is more than 13 dB. The main beam direction is normal to the ground plane. Finally CST EM Studio is used to validate the global best antenna candidate structure.
