A novel circular polarized dielectric antenna array (DRA) for millimeter-wave applications at 30 GHz is presented in this paper. The unit element array is a flower-shaped DRA fed with a cross slot. To obtain circular polarization, a sequential network combined with the cross slots is used to feed the 2×2 array. The prototype of the proposed antenna array is fabricated and measured to obtain a wide resonance bandwidth from 27 GHz to 38 GHz frequency band. Furthermore, this left-hand polarized antenna array has achieved a peak gain of 9.5 dBi with 3-dB axial ratio at 30 GHz. The proposed DRA array with wideband resonance and gain bandwidth has the potential to be used for millimeter-wave wireless communications at the 30 GHz band.
本文提出了一种用于30GHz毫米波应用的新型圆极化介质天线阵列(DRA)。单元阵列是一个由交叉缝隙馈电的花形DRA。为了获得圆极化,采用了与交叉缝隙相结合的顺序网络来馈电2×2阵列。制作并测量了所提出天线阵列的原型,以在27GHz至38GHz频段获得宽谐振带宽。此外,该左旋极化天线阵列在30GHz时实现了9.5dBi的峰值增益和3dB轴比。所提出的具有宽带谐振和增益带宽的DRA阵列具有用于30GHz频段毫米波无线通信的潜力。
