Influence of a novel periodic structure on patch antenna
Source abstract
Abstract
We used the method of finite-difference time domain (FDTD) to study the characteristics of the patch antenna based on a novel periodic structure, and the theory of photonic crystal structure (also photonic band gap [PBG]) structure was introduced. The results obtained show that the surface waves propagating along the substrate surface can be suppressed by the periodic structure due to the influence of its forbidden band, and the energy of the electromagnetic waves is concentrated mainly in the substrate. As a result, the patch antenna based on the periodic structure has a wider bandwidth in comparison with the conventional patch antennae; and a higher gain is reached, so the patch antenna’s performance is improved. Due to such the advantages, the application of patch antennae can be extended in such fields as mobile communication, satellite communication, aviation, etc.
