| Abstract(in English) | In this paper, a non-contact channel estimation method suitable for a miniaturized MIMO (Multiple-Input Multiple-Output) antenna using load modulation is proposed. In this technique, AUT (Antenna Under Test) is terminated by two-state variable loads, and the channel between AUT and receiving antenna is estimated by illuminating AUT with an external antenna and measuring a apparent propagation channel between transmitting and receiving antenna. Therefore, this method can estimate channel without connecting cable to AUT side with a fairly simple hardware. Numerical results show that proposed method achieves an accurate channel estimation compared to the conventional method, where the coaxial cables are connected to the AUT, and is suitable for the channel measurement of the miniaturized MIMO antenna. |
