Title:
MULTIPATH FADING PREVENTING DEVICE FOR RADIO COMMUNICATION EQUIPMENT
Document Type and Number:
Japanese Patent JP2002064327
Kind Code:
A
Abstract:
To provide a multipath fading preventing device for radio communication equipment, which does not increase an antenna installation area and can be installed at a low cost.
When there is a construct 25 such as a side wall or wire net on the roof of a building in a zone 24 close in the front of an antenna 21 of PTP radio communication equipment, radio wave absorbers 26 are stuck on the antenna side front face of this construct 25, namely, on the side face and upper surface of the construct 25 on the side of antenna. Thus, generation of reflected waves from the construct 25 can be suppressed and the incidence of indirect waves to an opposite antenna 21 can be prevented so that multipath fading can be prevented.
