Modeling of a patch antenna in Comsol Multiphysics finite element analysis program

The article evaluates in detail the capabilities of patch antennas application based on the analysis of their advantages and disadvantages. The new patch antenna design was subjected to modeling, including description of its structure and creation of a three-dimensional model. The field distribution in the patch antenna geometry was obtained, which gives a complete picture of the influence of its structural elements on the electromagnetic properties. The directional diagram of the patch antenna is obtained, which reveals the angular features of its radiation. Plots of the gain of a single patch antenna, the gain of an 8×8 uniform array, and the gain of an 8×8 microstrip patch antenna plotted in dB-scale are constructed. It is shown that the design of the rectangular microstrip patch antenna with V-shaped notches provides better polarization at the edges compared to the center in the proposed patch antenna model, which can be a critical factor in real-world applications, especially in areas where communication quality is subject to external influences. The frequency at which this antenna resonates is 1,403 GHz, this allows for a wider bandwidth and improved impedance matching. These results emphasize the promising potential of the investigated patch antenna design in modern communication technologies and wireless data transmission systems.
