本文提出了一种混合天线设计的光供电超高频（SHF）RFID应答器适用于集成到金属。该天线的主要特点是能够接收用于数据通信的超高频微波信号和用于转发器电源的光信号。天线的设计是基于一个圆形波导，其中填充有聚合物光纤，以引导光到光电二极管，以启动应答器。另外，在圆形波导内放置过渡，以将SHF信号的波导模式转换成微带模式，微带模式是更适合于集成电子应答器部件的结构。本文讨论了在这里提出的超高频微波和光的组合的限制和解决方案。此外，天线结构的增益进行了测量，并与模拟的。
This paper presents a hybrid antenna design for an optically powered super high frequency (SHF) RFID transponder applicable for the integration into metal. The key feature of the antenna is its ability to receive microwave signals at SHF for the data communication and optical signals for the power supply of the transponder. The antenna design is based on a circular waveguide which is filled with polymer optical fibers to guide light to the photodiodes to power up the transponder. Additionally a transition is placed within the circular waveguide to transfer the waveguide mode of the SHF signal into a microstrip mode which is a more suitable structure for the integration of electronic transponder components. This paper discusses the constraints and solutions for the here presented combination of SHF microwave and light. Furthermore, the gain of the antenna structure is measured and compared to the simulated one.
