摘要

提出了一种宽带双频双极化(DBDP)共享孔径阵列，该阵列采用新颖的L波段和C波段重叠叠片作为全阵列的单元格。通过避免穿孔，提高了低频段的阻抗带宽。为了验证重叠结构在相控阵应用的可行性，制作了DBDP单元电池原型。在L波段和c波段分别测量到17.6% (219 MHz)和15% (790 MHz)的阻抗带宽(|S11|≤-10 dB)，同时在这两个波段也证实了良好的辐射方向图。

Broadband dual-band dual-polarized overlapped antenna element

A broadband dual-band dual-polarized (DBDP) shared-aperture array is proposed, where the novel L- and C- band overlapped stacked patches are designed as the unit cell of full array. The impedance bandwidth in the lower band is enhanced by avoiding perforation. The DBDP unit cell prototype has been fabricated to validate the overlapped-structure feasibility for phased array applications. The impedance bandwidths (|S11| ≤ -10 dB) of 17.6% (219 MHz) and 15% (790 MHz) are measured in L- and C-band, respectively, while good radiation patterns are also confirmed in both bands.
