Abstract

A novel concept for a dual-polarized microstrip antenna array with a center frequency of 23.75 GHz is introduced. The array is composed of ten single square patch elements having equal resonance frequencies in both directions. The microstrip patches are rotated by 45 ° and linearly aligned to obtain a fan beam antenna characteristic. The feed structure is in seriesparallel configuration with best advantages in space saving. The antenna array is fully planar and compact but has nevertheless a very low cross-talk between its two orthogonal channels of <; -30 dB. The sidelobe level (SLL) of the antenna array is decreased to -16.8 dB by implementing an amplitude taper according to Dolph-Chebyshev (DC). The main beam direction for both polarizations of the antenna array is boresight, with a half-power beamwidth (HPBW) of 10 ° for φ = 0° and 100 ° for φ = 90°. By using an array of these fan beam antenna arrays, one-dimensional beamforming applications can be realized. Due to its high polarization purity, low sidelobe level and fan-beam characteristics, the antenna array can be used in 5G mobile applications.

一种串并联馈电结构的平面双极化微带天线阵列

提出了一种中心频率为23.75 GHz的双极化微带天线阵列的新概念。该阵列由十个在两个方向上具有相等共振频率的单个方形贴片元件组成。微带贴片旋转45°并线性排列以获得扇形波束天线特性。进给结构采用串并联配置，最节省空间。天线阵列是全平面且紧凑的，但其两个正交信道之间的串扰非常低。-30分贝。该天线阵的旁瓣电平(SLL)根据道尔夫-切比雪夫(dbp - chebyshev, DC)实现幅度渐变，降低至-16.8 dB。天线阵两个极化方向的主波束方向均为轴向，φ = 0°时的半功率波束宽度为10°，φ = 90°时的半功率波束宽度为100°。通过使用这些扇形波束天线阵列阵列，可以实现一维波束形成应用。该天线阵具有极化纯度高、旁瓣电平低、扇形波束等特点，可用于5G移动应用。
