Abstract

A multiresonance metasurface antenna is proposed which has wide bandwidth and low-profile. The characteristic mode theory is used to design antenna structure. Three ideal modes are obtained by adjusting the mode currents to optimize the radiation performance of the antenna. The characteristic mode analysis is used to model, analyze, and optimize the antenna, revealing the physical characteristics of the metasurface antenna. The slot is not only used as the feeding structure for exciting characteristic modes but also introduces a slot mode. Combining the slot mode with the metasurface modes, the bandwidth of the antenna is broadened. The antenna element has a relative bandwidth of 43.7%. To obtain higher gain, a 2 × 2 antenna array is proposed. The antenna array is simulated, fabricated, and measured. The results show that the relative bandwidth of the proposed metasurface antenna array is 31.6% with the gain of 12.3–15.8 dBi over the operating bandwidth.

具有多模谐振的宽带元面天线

本文提出了一种具有宽带宽和扁平外形的多谐振元面天线。天线结构设计采用了特征模理论。通过调整模态电流获得了三个理想模态，从而优化了天线的辐射性能。利用特征模分析对天线进行建模、分析和优化，揭示了元面天线的物理特性。槽不仅用作激发特征模的馈电结构，还引入了槽模。将槽模式与元面模式相结合，天线的带宽得到了拓宽。天线元件的相对带宽为 43.7%。为了获得更高的增益，提出了一个 2 × 2 天线阵列。对天线阵列进行了模拟、制造和测量。结果表明，所提出的元面天线阵列的相对带宽为 31.6%，在工作带宽上的增益为 12.3-15.8 dBi。
