Abstract

This article proposes a microstrip-to-microstrip (MS-to-MS) vertical transition with pixel structures and then proposes a knowledge-assisted proximal policy optimization (PPO), which is a reinforcement learning (RL) for the design of this transition. The transition requires fully connected structures and a novel mechanism to generate the pixel structures with fully connected shape is proposed and incorporated into PPO. The proposed method is compared with the particle swarm optimization (PSO) and the genetic algorithm (GA) and demonstrates benefits in improving design efficiency. The designed MS-to-MS transition is fabricated using the PCB process. Measurement results indicate that the designed MS-to-MS vertical transition operates in the band from 3.4 to 14.8 GHz with low insertion loss.
基于强化学习的宽带微带到微带垂直过渡像素结构设计
本文提出了一种具有像素结构的微带到微带(MS-to-MS)垂直过渡,然后提出了一种知识辅助的近端策略优化(PPO),这是一种用于这种过渡设计的强化学习(RL)。这种过渡需要完全连接的结构,提出了一种新的机制来生成具有完全连接形状的像素结构,并将其纳入PPO中。将该方法与粒子群算法(PSO)和遗传算法(GA)进行了比较,证明了该方法在提高设计效率方面的优势。设计的MS-to-MS转换采用PCB工艺制作。测量结果表明,所设计的MS-to-MS垂直转换工作在3.4 ~ 14.8 GHz频段,插入损耗低。
