提出了一种基于基片集成波导(SIW)的偶极子和环天线组合的高增益SIW椭圆极化天线，用于毫米波(mm波)。偶极子天线和环形天线由刻蚀在SiW顶层上的纵向缝隙差分激励。提出的电偶极子和环状天线的组合构成了平行的电偶极子和磁偶极子，在相同的相位信号激励下，电偶极子和磁偶极子辐射出两个正交的电场分量和远场辐射的90°相位差。该天线的实际增益为8.346 dBI，在60 GHz下的辐射效率为89.40%。
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.
