摘要

摘要:提出了一种基于衬底集成波导(SIW)技术的28ghz带内全双工通信微带馈电双差分天线。采用SIW腔高阶TE201模式和差分端口激励，在210 MHz带宽和8.2 dBi的高增益下实现了优于-77 dB的自干扰消除。该天线的小型化尺寸为7.56\ × 7.56\ \math {mm}^{2}$，辐射效率为77%，前后比为19 dB。

SIW Antenna for 5G In-Band Full Duplex Applications

Ahstract-This paper presents a microstrip fed, double differential antenna based on substrate integrated waveguide (SIW) technology for In-Band Full Duplex communication at 28 GHz. Using higher order TE201 mode of the SIW cavity and differential port excitations, the proposed antenna achieves a self-interference cancellation of better than -77 dB over a 210 MHz bandwidth and a high gain of 8.2 dBi. Occupying a miniaturized size of $7.56 \times 7.56\ \mathrm{mm}^{2}$, the antenna features a radiation efficiency of 77% and front to back ratio of 19 dB.
