非对称多模谐振天线研究综述OA

In this survey,the eigenmode sets of asymmetric multimode resonant antennas under different excitations are insightfully anatomized based upon the eigenmode theory.In terms of the symmetry of antenna structure,feeding and perturbation,a general classification method for asymmetric multimode resonant antennas is proposed,with history and milestones demonstrated.Furthermore,the design approaches to asymmetric multimode resonant antennas are comprehensively introduced,in terms of broadband or multi-band,circular polarization,and radiation dispersion controlling techniques.Finally,potential applications of asymmetric multimode resonant antennas in satellite communication,radar systems and anti-jamming communication systems are prospected.The survey is expected to be the design guidelines for engineering developments,as well as scientific researches of asymmetric multimode resonant antennas.
