摘要: 设计了一款具有高功率容量与宽角度扫描特性的C/Ku双频段共口径平面相控阵天线。在同一辐射口径内，相控阵天线包含有基于平面偶极子单元的C波段4×4阵列，以及基于混合零阶谐振贴片单元的Ku波段8×9阵列。所设计的相控阵天线的宽角度扫描性能归功于双频段阵元天线的宽波束辐射特性。下层混合零阶谐振贴片天线既能作为Ku波段的宽波束辐射单元，又能够为C波段的偶极子天线提供零反射相位，进而基于镜像原理拓宽偶极子天线的波束宽度。并且，对天线进行了介质埋入式设计，避免了空气击穿以提高天线系统功率容量。全波仿真结果表明，所提出的共口径相控阵天线在C和Ku双频段均实现了±45°的波束扫描，增益波动小于3 dB，天线阵列在各单元输入功率之和为1 W时功率容量达18.9 MW。Abstract: In this paper, a shared-aperture planar phased array antenna operated at C and Ku band with wide-angle scan and high-power capacity is designed. The proposed phased array contains a printed dipole element-based 4×4 C-band array and a Ku-band array composed of 9×8 hybrid zeroth-order resonance patch elements. The wide-angle scanning performance of the designed phased array attributes the success to the wide-beam radiation of the dual-band elements. The bottom zeroth-order resonance patch element can not only be used as the Ku-band wide-beam radiation element, but also supplies the zero-phased reflection for the C-band printed dipoles which generate the wide-beam patterns based on the image theory. Furthermore, the antenna is designed with all metals buried by substrates to avoid air breakdown, and thus to improve the power capacity of the phased array. Full-wave simulation results show that the designed array can obtain a ±45° beam scan with its gain fluctuation less than 3 dB in both C and Ku bands, and the power capacity of the array reaches 18.9 MW when the total input power is 1 W.
