摘要

在这项工作中,提出了一种集成基于石墨烯的倍频器和对角喇叭天线的毫米波/亚毫米波发射机原型。驱动信号在WR-28频段(26.5- 40ghz)内产生,输出信号在WR-3频段(220- 330ghz)内辐射。使用高精度3D打印技术制造了一个原型。比较了5、7和9倍阶的性能,在250 mm距离处测量的最大功率约为-45 dBm。同时也给出了测量的辐射图。

Millimetre wave transmitter based on a few-layer graphene frequency multiplier
In this work, a millimetre/submillimetre wave transmitter prototype integrating a graphene based frequency multiplier and a diagonal horn antenna is presented. With a driving signal in the WR-28 frequency band (26.5-40 GHz), an output signal in the WR-3 frequency band (220-330 GHz) is generated and radiated. A prototype has been manufactured using high precision 3D printing techniques. The performance with multiplication orders 5, 7 and 9 has been compared, obtaining maximum power levels of about -45 dBm, measured at a distance of 250 mm. Measured radiation patterns are also presented.
