Abstract

In this study, an omnidirectional and high-performance free-standing monopole patch radio-frequency antenna was fabricated using a urea-functionalized phosphorene/TiO/polypyrrole (UTP) nanocomposite. The UTP nanocomposite antenna was fabricated via ball milling of urea-functionalized phosphorene, chemical oxidative polymerization of the UTP nanocomposite, and mechanical pelletizing of the composite. Based on experiments, the proposed UTP nanocomposite-based antenna exhibited long-term stability in terms of electrical conductivity. After 12 weeks, a slight change in surface resistance was observed. The proposed antenna exhibited high radiation efficiency (78.2%) and low return loss (-36.6 dB). The results of this study suggest the potential of UTP nanocomposite antennas for applications in 5G technology.

摘要

在本研究中，使用尿素功能化的磷烯/二氧化钛/聚吡咯（UTP）纳米复合材料制备了一种全向高性能独立单极贴片射频天线。UTP纳米复合材料天线是通过对尿素功能化的磷烯进行球磨、UTP纳米复合材料的化学氧化聚合以及复合材料的机械造粒来制备的。基于实验，所提出的基于UTP纳米复合材料的天线在电导率方面表现出长期稳定性。12周后，观察到表面电阻有轻微变化。所提出的天线表现出高辐射效率（78.2%）和低回波损耗（-36.6 dB）。本研究结果表明UTP纳米复合材料天线在5G技术应用中的潜力。
