摘　　要：滤波器、天线等微波无源器件是现代微波通信系统中必不可少的组成部分.但是,随着无线通信技术的飞速发展,微波无源器件不断小型化、复杂化,器件对尺寸精度要求愈加严格,传统加工工艺在制备小型化复杂结构微波元器件上出现了制约.而增材制造技术(3D打印)是一种快速、绿色、高精度的新兴制造技术,具有不需要模具、人工成本低、材料利用率高、成型精度高、可制备复杂结构的优点,为企业和个人的生产与设计带来革命性的变化.对于成型精度要求高、结构设计较为灵活的微波无源器件而言,增材制造的出现使其摆脱了传统制造工艺的束缚,进而更多结构复杂、性能优异的器件得以实现,因此增材制造技术对于微波无源器件的生产与设计具有重要意义.本文主要介绍了增材制造特点、增材制造原材料的研究现况,并论述了增材制造技术在微波无源器件设计和制备过程中的应用,最后阐述了增材制造微波无源器件面临的挑战与机遇,为今后微波无源器件的增材制造科学研究及工程应用提供了一定的参考作用.Passive microwave devices are an indispensable part of modern microwave communication systems,such as filters and antennas.However,with the rapid development of wireless communication technology,the continuous miniaturization of passive microwave devices,and the complexity of device structure,the machining precision of microwave devices is becoming increasingly stringent.Therefore,traditional processing technology has a restriction in the fabrication of miniaturized complex microwave devices.Additive manufacturing(3 D printing)is a rapid,green,high-precision emerging manufacturing technology,which has the advantages of low labor costs,high material utilization,and high precision.It can directly fabricate complicated geometries without a mold,and can revolutionize the way we design and manufacture for enterprises and individuals.Furthermore,by eliminating the constraints of traditional processing,additive manufacturing makes it possible to produce more complex structures and high-performance devices.Thus,additive manufacturing is of great significance for producing and designing passive microwave devices.In this paper,the characteristics and materials of additive manufacturing are introduced.We discuss the applications of additive manufacturing in the design and fabrication process of passive microwave devices.We also elaborate on the challenges and opportunities of additive manufacturing for passive microwave devices,which may provide a reference for future research and engineering applications.
