A conformal receiver‐transmitter metasurface (MS) for high gain conformal Fabry‐Perot (FP) resonator antenna is presented in this article. The meta‐atom consists of three layers of metal structures and two layers of supporting structures. The three layers of metal structures, including receiver patch, radiator patch and ground plane, are printed on ultra‐thin substrates. The reception and radiation of the meta‐atom are separated by the ground plane, in which case, the reflection and transmission coefficients of the meta‐atom can be tuned independently. This property enables the MS to realize transmission phase compensation while maintain the reflection coefficient constant. Also, the supporting structures are fabricated by 3D printing technology, thus they can be fabricated into cylinder and the metal structures on ultra‐thin substrates are easily conformed to them. A conformal patch feed antenna is designed in the same way. Then the conformal FP resonator antenna is formed by the MS and the feed antenna. Through tuning the transmission phase of each meta‐atom, the MS can make the wave coming out of the cavity appear as a nearly plane wave. The peak gain of the conformal FP resonator antenna reaches 18 dB with aperture efficiency of 58.5%. Fine radiation pattern and high gain property are obtained by the conformal resonator antenna. The measured results verify the performance of the proposed conformal antenna. The design in this article can greatly promote the practical application of the FP resonator antenna.

法布里-珀罗谐振器天线应用的3D打印共形超表面

本文介绍了用于高增益保形法布里-珀罗（FP）谐振器天线的保形收发器超表面（MS）。准原子由三层金属结构和两层支撑结构组成。三层金属结构，包括接收器贴片，辐射器贴片和接地层，印刷在超薄基板上。偏原子的接收和辐射被接地平面隔开，在这种情况下，偏原子的反射和透射系数可以独立调整。此属性使MS能够在保持反射系数恒定的同时实现传输相位补偿。而且，支撑结构是通过3D打印技术制造的，因此，它们可以制成圆柱体，并且超薄基板上的金属结构很容易与它们吻合。保形贴片馈电天线的设计方法相同。然后，由MS和馈电天线形成共形FP谐振器天线。通过调整每个亚原子的传输相位，质谱仪可以使从腔中出来的波看起来像是一个平面波。保形FP谐振器天线的峰值增益达到18 dB，孔径效率为58.5％。通过共形谐振器天线可以获得良好的辐射方向图和高增益特性。测量结果验证了所建议的保形天线的性能。本文的设计可以极大地促进FP谐振器天线的实际应用。然后，由MS和馈电天线形成共形FP谐振器天线。通过调整每个亚原子的传输相位，质谱仪可以使从腔中出来的波看起来像是一个平面波。保形FP谐振器天线的峰值增益达到18 dB，孔径效率为58.5％。通过共形谐振器天线可以获得良好的辐射方向图和高增益特性。测量结果验证了所建议的保形天线的性能。本文的设计可以极大地促进FP谐振器天线的实际应用。然后，由MS和馈电天线形成共形FP谐振器天线。通过调整每个亚原子的传输相位，质谱仪可以使从腔中出来的波看起来像是一个平面波。保形FP谐振器天线的峰值增益达到18 dB，孔径效率为58.5％。通过共形谐振器天线可以获得良好的辐射方向图和高增益特性。测量结果验证了所建议的保形天线的性能。本文的设计可以极大地促进FP谐振器天线的实际应用。保形FP谐振器天线的峰值增益达到18 dB，孔径效率为58.5％。通过共形谐振器天线可以获得良好的辐射方向图和高增益特性。测量结果验证了所建议的保形天线的性能。本文的设计可以极大地促进FP谐振器天线的实际应用。保形FP谐振器天线的峰值增益达到18 dB，孔径效率为58.5％。通过共形谐振器天线可以获得良好的辐射方向图和高增益特性。测量结果验证了所建议的保形天线的性能。本文的设计可以极大地促进FP谐振器天线的实际应用。
