【摘要】 本文提出了一种紧凑的双频双极化微带天线阵列,具有宽频带和低剖面特性。该阵列采用堆叠结构,由两种具有高隔离度的共享孔径双频正交极化子阵列组成。由于激发相邻模式,在单个矩形贴片上堆叠四个寄生贴片能够增加阻抗带宽,每对辐射单元共享两个寄生单元以实现双频单元的小型化。通过倒角处理增加带宽,在双频的高频段上开缝以调整耦合频率。更多还原

【Abstract】 This article presents a compact dual-band dual-polarized microstrip antenna array with wide bandwidth and low profile characteristics.The array adopts a stacked structure and is composed of two shared-aperture dual-band orthogonal-polarized sub-arrays with high isolation.Due to the excitation of adjacent modes,stacking four parasitic patches on a single rectangular patch can increase the impedance bandwidth.Each pair of radiating elements shares two parasitic elements to achieve the miniaturization of the dual-band elements.The bandwidth is increased by chamfering,and slots are opened in the high-frequency band of the dual-band to adjust the coupling frequency.更多还原
