摘要

与多天线解决方案相反，带内全双工(IBFD)系统可以利用共享天线进行信号传输和接收，以减少设备的外形因素。然而，这些单天线设计必须额外考虑由天线阻抗不匹配反射产生的自干扰(SI)。本文研究了不同的天线负载和传输线长度对商用磁环行器和全向天线组件在2和6 GHz之间工作的影响。结果表明，负载阻抗和天线与接口器件之间的距离都会对复合SI的频率选择性产生较大影响，从而影响IBFD系统的整体带宽。

Antenna Reflections in Shared-Antenna In-Band Full-Duplex Systems : (Invited Paper)

As opposed to multiple-antenna solutions, in-band full-duplex (IBFD) systems can utilize a shared antenna for signal transmission and reception to reduce the device form factor. These single-antenna designs, however, must additionally consider the self-interference (SI) that is generated by antenna impedance-mismatch reflections. This paper investigates the effect of different antenna loads and transmission line lengths for commercially-available magnetic circulator and omnidirectional antenna components operating between 2 and 6 GHz. The results indicate that both the load impedance and the distance between the antenna and interface device can drastically impact the composite SI frequency-selectivity, which influences the overall IBFD system bandwidth.
