描述了由 35 个 x 极化和 32 个 y 极化 Vivaldi 天线制成的面包板的详细设计和 RF 分析，这些天线彼此间隔 0.67 波长并位于有限接地平面上方。面包板构成馈源阵列的代表性部分，为用于海洋观测的下一代微波辐射计提供锥形扫描或推扫式天线的照明。分析在 6.9 GHz 频率下完成，包括元件之间的相互耦合，并在两个商业软件（即 CST 和 GRASP 的 MoM 附加软件）中完成。
The detailed design and RF analysis of a breadboard made by 35 x-polarized and 32 y-polarized Vivaldi antennas, placed 0.67 wavelength from each other and located above a finite ground plane, are described. The breadboard constitutes a representative part of the feed array illuminating a conical scan or push-broom antenna for next generation microwave radiometers for ocean observation. The analysis are done at 6.9 GHz including mutual coupling between the elements, and in two commercial software, i.e. CST and the MoM add-on to GRASP.
