An Improvement of Antenna Bandwidth in Microstrip Patch Antenna with the Insertion of PBG Structure
Antenna design has grown more rigorous and difficult over the years due to the phenomenal development of portable wireless devices that require miniature antennas with improved performance. Microstrip antennas are widely used in such portable wireless devices. In order to overcome the inherent limitations of microstrip antennas such as narrow bandwidth, lower gain, excitation of surface waves etc., a new solution technique using Photonic Band Gap (PBG) materials, as substrates has attracted increasing attention recently. These periodic structures have the unique property of preventing the propagation of electromagnetic waves for specific frequencies and directions that are defined by the shape, size, symmetry, and the material used in their construction by creating periodic stop bands in their dispersion diagram. In this work, a rectangular microstrip antenna over a PBG is designed and simulated at 7.5 GHz and a significant enhancement of the performance has been observed in compared with the conventional design. The results are presented in the text.
