Y-Shaped Time-Domain Ultra-Wideband Antenna Array

The characteristics of a Y-shaped time-domain ultra-wideband antenna array are analyzed in this paper. The structure of the array is planar and composed of three linear arrays with constant 120-degree adjacent angle around one common endpoint. Radiation performances, including the fidelity of waveform and directional energy patterns of radiated signals can be obtained by the change of array parameters. Simulation results indicate that the energy beam of radiated signals can be steered to arbitrary direction in space through the time delay configurations of each array element, and furthermore, the optimal fidelity of waveforms can also be achieved in the maximum radiation direction at the same time.
