【摘要】 本文提出了一种基于介质谐振器的双频同时双极化的共口径相控阵天线单元,高频段采用氧化铝陶瓷材料的圆柱形介质谐振器,实现相对带宽为38.8%,低频段采用罗杰斯3006材料的金属环加载的阶梯状圆柱介质谐振器,实现相对带宽为35.3%。在物理口径1.33λ_g*1.33λ_g(λ_g为高频段的最高频的波长)上实现4个高频段天线和一个低频段天线同时双极化架构,满足多功能复合相控阵雷达的使用需求。更多还原

【Abstract】 This paper presents a dual-band and dual-polarized shared-aperture phased array antenna element based on dielectric resonators.For the high-frequency band antenna,a cylindrical dielectric resonator(DR) fabricated from alumina ceramic is employed,achieving a relative bandwidth of 38.8%.For the low-frequency band antenna,a stepped cylindrical dielectric resonator loaded with a metallic ring and constructed from Rogers 3006 substrate material is utilized,achieving a relative bandwidth of 35.3%.Within a physical aperture of 1.33λ_g×1.33λ_g(where λ_g represents the wavelength at the highest frequency of the high-frequency band),the shared-aperture phased array antenna element integrates four high-band elements and one low-band element,and all antennas support dual-polarization.This design fulfills the requirements for multifunction composite phased array radar applications.更多还原
