Design of monopole antennas with various grounds for 2.4 GHz applications
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.
