摘要

介绍了用于带内全双工通信的同轴馈电正交极化宽带矩形螺旋天线的设计、实现及其隔离性能。在一个基板系统上紧密地设计和实现了RHCP和LHCP两种天线。给出了所实现天线的隔离性能和辐射方向图。在2.2 GHz (2.5 ~ 4.7 GHz)的−10db阻抗带宽范围内，端口间的隔离度为−33.5 dB ~−21.5 dB。

Broadband antenna for passive self-interference suppression in full-duplex communications

This paper presents the design, implementation and isolation performance of coaxially fed orthogonally polarized broadband rectangular spiral antenna for in-band full duplex communications. Two antennas one with RHCP and other with LHCP are designed and implemented close together on one substrate system. Measured isolation performance and radiation patterns of implemented antennas are presented. Within −10 dB impedance bandwidth of 2.2 GHz (2.5–4.7 GHz), the isolation between ports varies from −33.5 dB to −21.5 dB.
