Abstract :
Applying the electromagnetic numerical method, the radiation characteristic in time domain of the electric-magnetic vibrator combined ultrawideband (UWB) antenna array was investigated. The power pattern and radiated character on main axis of different arrays structure and space were analyzed. The coupling between the antenna units was estimated through comparing it with no-coupling model. The results indicate that the electric-magnetic vibrator combined UWB antenna array can improve antenna direction and radiated character on main axis.
