Influence of EBG Structures on the Far-Field Pattern of Patch Antennas
In this paper, the influence of the EBG structures on the far-field pattern of patch antennas is investigated. As a reference model, a conventional rectangular patch antenna on a high-permittivity substrate is used. The reference model is consequently equipped by an EBG substrate (instead of the conventional one), and by an EBG cover (so called EBG superstrate). The changes in the farfield radiation patterns are discussed. In the second part of the paper, the substrate is perturbed by two different EBG structures designed for the coverage of two operation bands.
