Abstract：Electric field coupling antenna is a new type of antenna that can be used in high speed wireless communication at a very short distance. It is the working antenna for TransferjetTM technology promoted by Sony Corporation. In this paper, we use the high frequency structure simulator to design a typical antenna of this kind with parametric structures. We analyze the influences of the length (Ls) and width (Ws) of the short stub, the height (H) of coupling electrode on the performance of the antenna corresponding to the centre frequency and bandwidth. We also analyze the effects of the distance (d) and angle (θ) between two antennas and the size of coupling electrode (Lc) on transmission loss. Finally, we design an antenna satisfying the technology standards of TransferjetTM, thus demonstrate its working performance.
