Comparison of Multi-resonant Patch Antenna Topologies

This article discusses one of the principles for increasing the bandwidth of patch antennas based on the multi-resonance method. To solve this problem, electrodynamic modeling of the "basic" multi-resonance patch antenna, its optimization, as well as the creation of two additional antennas, built on the principles of this method, were carried out. A comparative analysis of the obtained characteristics of these antennas in the electrodynamic design program ANSYS HFSS and prototypes is carried out.
