Abstract :
In this paper, we propose a novel method for measuring a complex radiation pattern of MIMO (Multiple-Input Multiple-Output) antennas, without connecting cables or small oscillators at ports of MIMO antennas. Results of the numerical simulation show that the proposed method gives the complex radiation pattern accurately when the signal-to-noise ratio at the receiving antenna is higher than 15 dB.
