虽然基片集成波导（SIW）技术已被广泛用于在刚性印刷电路板上制造微波电路，并且最近文献中出现了第一批纺织SIW天线的实现，但到目前为止，还没有完整的SIW微波组件。因此，本文介绍了设计，制造和测试的一类新的纺织品微波组件的可穿戴应用，实现基片集成波导技术。在表征所采用的纺织织物材料的电气性能方面，它示出，折叠的纺织SIW组件，如互连，滤波器和天线，形成可穿戴微波电路的优秀的积木，因为它们的低姿态，灵活性，和稳定的特性下弯曲和接近人体。因此，它们允许充分利用为可穿戴电子设备的部署而提供的大面积服装。除了基片集成波导互连，一个折叠的纺织基片集成波导滤波器工作在2.45 GHz的设计和测试。该滤波器结合了目标频段内的出色性能和良好的带外抑制，即使考虑到制造过程中的容差也是如此。最后，一个折叠基片集成波导背腔贴片天线的制作和实验验证在现实的工作条件。
Although substrate integrated waveguide (SIW) technology is well established for the fabrication of microwave circuits on rigid printed circuit boards, and the first implementations of textile SIW antennas have recently appeared in literature, up to now, no complete set of SIW microwave components has been presented. Therefore, this paper describes the design, manufacturing, and testing of a new class of textile microwave components for wearable applications, implemented in SIW technology. After characterizing the adopted textile fabrics material in terms of electrical properties, it is shown that folded textile SIW components, such as interconnections, filters, and antennas form excellent building blocks for wearable microwave circuits, given their low profile, flexibility, and stable characteristics under bending and in proximity of the human body. Hence, they allow the full exploitation of the large area garments offered for the deployment of wearable electronics. Besides SIW interconnections, a folded textile SIW filter operating at 2.45 GHz is designed and tested. The filter combines excellent performance in the band of interest with good out-of-band rejection, even when accounting for the tolerances in the fabrication process. Finally, a folded SIW cavity-backed patch antenna is fabricated and experimentally verified in realistic operating conditions.
