In order to study the radiation characteristics of the airborne VHF antenna, the model of the knife-type antenna was achieved by FEKO. Using MoM analyzed the radiation characteristics of the antenna in free space and using MLFMM analyzed the radiation characteristics of the airborne antenna. By comparing the VSWR and radiation pattern of the knife-type antenna in free space and in airborne state,...
According to the reflection condition of optics Bragg, two kinds of two-dimensional curved EBG structures are designed and their bandgap characteristics are observed, and they are applied to the cylindrical conformal microstrip antennas for the first time. The simulation results indicate that, the higher harmonics of the antenna with EBG are perfectly suppressed comparing with the normal cylindrical...
