Description
The paper proposes a new type of multiband broadband printed antennas with a chaotic outline. To synthesize them, the topologies for solving the traveling salesman problem based on the ant colony optimization algorithm are used. Removal of topological restrictions on the trajectory of traversing the matrix of cities made it possible to switch from meander-type antenna structures to antennas with chaotic geometry. In this case, the requirement on the restriction is fulfilled, according to which the trajectories of traversing the matrix of cities should not have mutual intersections. In the course of the research, several design options were considered, which differ in the variation of the antenna parameters. For their synthesis and analysis, the Numerical modeling methods were used due to the complexity of describing the interaction of antennas of non-Euclidean geometry with radio waves. Evaluation and comparison of proposed antennas held by the following characteristics: amplitude-frequency response and voltage standing wave ratio.
