手征介质偶极子天线研究
THE STUDY ON THE CHIRO-OMEGA DIPOLE ANTENNA
-
摘要: 本文首先探讨了用手征介质作为微带天线基片的可能性。应用广义谱域指数矩阵方法,分析了单层和双层手征介质中所有单元的三种不同取向对偶极子天线辐射特性的影响,以及偶极子方向图随手征介质损耗正切的变化情况。Abstract: The possibility of using chiro-omega media as the substrates of microstrip antennas is discussed. With the help of the generalized spectral domain-exponential matrix technique, the far-field behaviour of dipole antenna is analysed in detail, which is located on the surface of one-layer, two-layer chiro-omega substrates, respectively, and the effects of the orientation of , chirality and -parameter on the radiation patterns are demonstrated. The lossy effect of chiro-omega substrates are also taken into consideration.
