Abstract

In this work we presented the design and comparative analysis of monopole antennas with various grounds, such as solid, wire-grid (WG), and sparse WG. The design details of sparse WG structures using the optimal current grid approximation (OCGA) and its modifications with changed grid element elimination tolerance are presented. Notably, the mass and surface area of the sparse WG structures are smaller than those of the original WG structure and significantly smaller than those of the solid structure. The mass and surface area of the sparse WG structures are reduced up to 13 and 7 times, respectively, compared to the solid structure. Comparisons of antenna characteristics show good agreement between the simulation results and the experimental results obtained for the solid structure, original and sparse WG structures. In some cases, the antenna characteristics of the sparse WG structures are even slightly better than those of the original WG and solid structures. The comparative analysis further demonstrates the effectiveness of OCGA and its modifications in creating sparse WG antennas. They can be used as a replacement for the solid structure, while significantly reducing the antenna mass and maintaining the required antenna characteristics.

2.4 GHz应用中各种接地单极天线的设计

在这项工作中，我们提出了单极天线的设计和比较分析与各种接地，如固体，线网格（WG）和稀疏的WG。介绍了基于最优电流网格逼近法（OCGA）的稀疏网格结构的设计细节，以及该方法随网格元消差公差的变化而进行的改进。值得注意的是，稀疏WG结构的质量和表面积比原始WG结构小，明显小于固体WG结构。与固体结构相比，稀疏结构的质量和表面积分别减少了13倍和7倍。仿真结果表明，固体结构、原始结构和稀疏结构的天线特性与实验结果吻合较好。在某些情况下，稀疏WG结构的天线特性甚至略好于原始WG和固体结构。对比分析进一步证明了OCGA及其改进方法在创建稀疏WG天线方面的有效性。它们可以作为固体结构的替代品，同时显著减少天线质量并保持所需的天线特性。
