【摘要】 本文提出了一种基于口径耦合的宽带双极化微带阵列天线。通过倒置寄生贴片与主辐射贴片构造双谐振模式,结合H形缝隙耦合馈电技术,显著拓宽了天线阻抗带宽。该天线在9～10.2 GHz频带内实现VSWR<2(相对带宽12.5%),经泰勒加权馈电网络优化,副瓣电平降至-18 dB,端口隔离度优于25 dB,增益超22 dBi,满足天线设计需求。更多还原

【Abstract】 A broadband dual-polarized microstrip array antenna based on aperture coupling is proposed in this paper.Via dual-resonance operation established by an inverted parasitic patch and main radiating patch with H-slot coupled feeding,the impedance bandwidth is significantly enhanced.The antenna achieves VSWR<2 at 9～10.2 GHz(12.5% bandwidth),with Taylor-weighted feed network optimization reducing sidelobes to-18 dB.Port isolation exceeds 25 dB and gain surpasses 22 dBi,fulfilling antenna design requirements.更多还原
