Electronic Band Gap Structure And Applications In Antenna. You discover a customized FDTD method of EBG analysis. Daniel Sievenpiper wrote it. Microstrip antennas integrated with electromagnetic band-gap EBG structures. In this paper a mushroom-like EBG structure is analyzed using the finite-difference time-domain FDTD method.
In this paper we discuss the use of electromag-netic band gap EBG structures in antenna engineering from a practical point of view. It implies that the electromagnetic response of metamaterials MTMs is unachievable or unavailable in conventional materials. To enhance the radiation efficiency of the antennas electromagnetic band gap EBG structures are used but they operate over a narrow band. Its band-gap feature of surface-wave suppression is demonstrated by exhibiting the near field distributions of the electromagnetic waves. In this chapter the EBG structures are integrated into microstrip patch antenna designs and their surface wave band gap property helps to increase the antenna gain minimize the back lobe and reduce mutual coupling in array elements. Electromagnetic Band Gap Structures in Antenna Engineering Featuring a wealth of practical examples and complete design details this dynamic resource offers a comprehensive applications-oriented survey of the state-of-the art in EBG engineering and explains the theory analysis and design of EBG structures.
However as applications move to higher frequencies conventional patch antenna designs encounter severe limitations such as narrow bandwidth low gain.
The antenna comprises an elliptical patch stub loading to shift the band to lower bands and an electronic bandgap structure on the ground side. It helps you to understand EBG applications in antenna engineering through an abundance of novel antenna concepts a wealth of practical examples and complete design details.
