Development of EBG-based phased-array mm-wave antennas

光学科学和微波领域的研究人员称之为光子带隙（PBG）和电磁带隙（EBG），以表示在某些频段抑制电磁波传播的结构。 在过去的几年里，这种结构一直是深入研究的主题。EBG技术迄今已广泛应用于光学应用，如：引导，色散工程，自准直，波长复用，负折射，等在这个建议的核心在于开发的理论基础和新颖的实用方案，利用EBG概念的EBG为基础的相控阵天线的建设是天线系统，包括在多个天线单元。新兴应用的向上频移和天线集成到RF电路的总体趋势强烈证明了所提出的调查的必要性。

Researchers in the fields of optical sciences and microwaves have dubbed the terms Photonic Bandgap (PBG) and Electromagnetic Bandgap (EBG) to signify structures that inhibit the propagation of electromagnetic waves at certain frequency bands. Such structures have been the subject of intense research in the past few years. The EBG technology has thus far been widely applied in optical applications such as: guiding, dispersion engineering, self-collimation, wavelength multiplexing, negative refraction, and etc. At the core of this proposal lies the development of a theoretical basis and novel practical schemes for the utilization of EBG concepts in the construction of EBG-based phased-array antennas which are antenna systems that consist in multiple antenna elements. The upward frequency shift of emerging applications and the general trend of integration of antennas into RF circuitry strongly justify the necessity of the proposed investigation.
