Study on Single Channel Full-Duplex Wireless Communication

单信道全双工无线通信提高了带宽利用率。为了实现单信道全双工无线通信，需要将接收天线处来自发射天线的自干扰降低到背景噪声水平。另外，为了扩大单信道全双工无线通信的应用范围，要求无线通信在水平面内具有全向性。我们正致力于开发一种在水平面内具有全向方向图并能减少自干扰的平面天线。我们证实，发射天线和接收天线之间的隔离度在2.4GHz频段大于60dB，辐射方向图是全向的水平面。

Single channel full-duplex wireless communication increases the efficiency of the bandwidth utilization. In order to realize single channel full-duplex wireless communication, reducing the self-interference at the receive antenna from the transmit antenna to the background noise level is needed. In addition, omni-directinal in horizontal plane is required for wireless communication in order to extend the range of applocation of single channel full-duplex wireless communication. We are working on developing a planar antennathat has omni-directional pattern in horizontal plane andd can reduce self-interference. We confirm that the isolation between transmit antenna and receive antenna is more than 60dB in 2.4GHz band and the radiation pattern is omni-directional in the horizontal plane.
