摘要

本文提出了一种新一代微带贴片天线，该天线采用可回收的低成本软聚合物聚氨酯(εr≈3.5 at 10ghz)作为介电衬底。将简单的制膜工艺与PU的低杨氏模量(EPU≈30 MPa)相结合，应用于x波段天线。采用膜支撑技术降低了高介电损耗(10 GHz时tan δ≈0.1)的影响，提高了天线的辐射效率(η≈31.7%)。此外，薄膜偏转使天线的频率可调性高达4.17%。最后，讨论了对金属贴片进行图像化处理以提高驱动性能的可行性。

Polymer micro-actuator for frequency agile patch antenna

In this paper, we present a new generation of microstrip patch antenna using a recyclable and low cost soft polymer, the polyurethane (εr ≈ 3.5 at 10 GHz) (PU), as a part of dielectric substrate. The combination of simple membrane manufacturing process and the low Young's modulus of PU (EPU ≈ 30 MPa) are employed in the X-band antenna application. Membrane supported technology is used to reduce the influence of this high dielectric loss (tan δ ≈ 0.1 at 10 GHz) and gives higher antenna radiation efficiency (η ≈ 31.7 %). Besides, membrane deflection allows frequency tunability of the antenna up to 4.17 %. At last, the interest of patterning the metallic patch was discussed in order to increase actuation performance.
