摘要

提出了一种适用于毫米波应用的低交叉极化微带天线阵列。天线单元由带过孔的对称t形贴片组成。采用双面对称辐射贴片结构可以抑制交叉极化电场，过孔减少了沿天线贴片传输时的能量泄漏。为了验证这个概念，制作了一个1 × 8的天线阵列并进行了测量。天线阵列−10db阻抗测量值为28.4% (31ghz - 41.5 GHz)，峰值增益为15dbi。交叉极化比大于35 dB, e面和h面3db波束宽度分别为7.5°和135°。所提出的小尺寸和低交叉极化天线阵列可能是相控阵雷达和第五代(5G)移动通信应用的良好选择。

A Low Cross-Polarization Microstrip Antenna Array for Millimeter Wave Applications

A low cross-polarization microstrip antenna array for millimeter wave (mmW) applications is proposed in this paper. The antenna element is composed of symmetric T-shaped patches with vias. The adoption of a double-sided symmetric radiation patch structure can suppress the cross-polarized electric field, and the vias reduces energy leakage during the power transmission along the antenna patches. To verify the concept, a 1 × 8 antenna array is fabricated and measured. The measured −10 dB impedance of the antenna array is 28.4% (31 GHz–41.5 GHz) and the peak gain is 15 dBi. The cross polarization ratio is above 35 dB and the 3 dB beamwidths on E-plane and H-plane are 7.5° and 135°, respectively. The proposed compact size and low cross-polarization antenna array might be a good choice for phased array radar and 5th generation (5G) mobile communication applications.
