Abstract :
Four-dimensional (4D) antenna arrays are formed by introducing a new dimension, time, into traditional arrays operating in 3D space. In this paper, the fundamental working principle of the 4D array is firstly introduced by studying the radiation pattern in the time and frequency domain, respectively. Then, the directional modulation effect on signals transmitted by the 4D array is introduced based on the transmitted signal spectrum analysis. Finally, BPSK signal transmission through the 4D array is studied to demonstrate the effect. Different from traditional arrays, the 4D array transmits direction-modulated signals, which is beneficial for secure communication.
