920 MHz / 2.45 GHzのデュアルバンドを用いるヘッドマウントディスプレイ通信に向けた伝搬特性解析

抄録

We investigated wireless communication with 920 MHz and 2.45 GHz bands around the human body to ensure the user’s mobility in a head-mounted display system. The electric field distribution and path loss characteristics were calculated based on electromagnetic field analysis, focusing on the positional relationship between the antennas and the body. As a result, it was shown that the path loss characteristics are frequency-dependent in the LOS and NLOS environment with the body. Therefore appropriate band selection provides stable communication.
