Abstract

PURPOSE:To constitute the inside of house as independent electromagnetic wave space from external part, by providing electromagnetic wave reflection body or absorbing body on the open type transmission line and mounting directional antenna on the mobile body to keep low leakage level to external the house. CONSTITUTION:The open type transmission line 7 is installed just above the running path of mobile body 5 on the ceiling of the house 1, and the reflection body 8 having the width W more than the half wave length of used center frequency is placed on the line 7. The mobile body 5 is provided with the directional antenna 9, and the direction of directivity is toward the open type transmission line 7. The electromagnetic waves emitted from the directional antenna 9 are received on the open type transmission line 7 and reflected downward with the reflection plate 8, and they propagate in the house 1 in multiplex reflection and the leakage outside the house 1 is low.
