3D打印用于开发带有有源射频电路组件的宽带多层天线系统的能力仍然相对未被探索。为了解决这一问题，本文演示了一种集成了极化选择开关的宽带贴片天线。天线带宽通过定制基板厚度和堆叠贴片层来增强。Switch集成了3D垂直转换，以实现更宽的带宽，更小的封装和低损耗。为了实现未来天线阵列的应用，还提出了通过调整衬底厚度和沉积工艺来最大化微带馈线性能的详细研究。天线由13个介电层和导电层组成。具体来说，该手稿展示了文献中完全印刷微带线的最低衰减，在18 GHz下测量损耗为0.25 dB/cm。该天线的辐射效率超过80%，带宽为45%。极化开关嵌入在所述天线结构内。由于三维馈线过渡和开关相对于天线馈线的对称位置，天线保持了~20 dB的高交叉极化比。
Capability of 3D printing for developing wideband multilayered antenna systems packaged with active RF circuit components remains relatively unexplored. To address this gap, this manuscript demonstrates wideband patch antenna that is integrated with a polarization selection switch. Antenna bandwidth is enhanced with customized substrate thicknesses and stacked patch layers. Switch is integrated with 3D vertical transitions to achieve wide bandwidth, smaller packaging, and low-loss. To enable future antenna array applications, a detailed investigation is also presented to maximize the performance of the microstrip feed lines by adjusting the substrate thickness and deposition process. The antenna consists of 13 dielectric and conductive layers. Specifically, the manuscript demonstrates the lowest attenuation in the literature for a fully printed microstrip line with 0.25 dB/cm measured loss at 18 GHz. The antenna operates with more than 80% radiation efficiency and 45% bandwidth. The polarization switch is embedded within the antenna structure. The antenna retains a high cross-polarization ratio of ~20 dB due to 3D feed line transitions and symmetric location of the switch with respect to the antenna feeds.
