摘要

提出了一种基于基片集成波导(SIW)的高增益SIW椭圆极化天线，用于毫米波(mm-wave)应用。偶极子和环形天线通过在SIW顶层蚀刻纵向槽来差分激励。所提出的偶极子与环形天线组合形成平行的电偶极子和磁偶极子，在相同的相位信号激励下，其远场辐射出两个正交的电场分量和$90^{\circ}$相位差。该天线在60 GHz时的实现增益为8.346 dBi，辐射效率为89.40%。

A High Gain SIW Elliptically Polarized Antenna for Millimeter-Wave Applications

A high-gain SIW elliptically polarized antenna combination of a dipole and loop antenna based on substrate-integrated waveguide (SIW) is proposed for millimeter-wave (mm-wave) applications. The dipole and loop antenna are differentially excited by a longitudinal slot etched on the top layer of SIW. The proposed combination of dipole and loop antenna forms a parallel electric dipole and magnetic dipole, which radiates two orthogonal electric field components and $90^{\circ}$ phase difference in the far-field radiation when they are excited with the same phased signal. The proposed antenna achieves a realized gain of 8.346 dBi, with a radiation efficiency of 89.40% at 60 GHz.
