Abstract

A waveguide includes a waveguide body which is hollow inside and made from a shape-retentive material, and a conductive inner coating layer which is electrically conductive and provided on an inner surface of the waveguide body. The waveguide uses an inner space of the conductive inner coating layer as a transmission path to transmit electromagnetic waves as signals. Two electric wires provided along the outer surface of the waveguide body serve respectively as a power line and a ground line to transmit electric power.

First claim

What is claimed is:

1. A waveguide for an in-vehicle communication system, comprising:
a waveguide body which has a hollow interior and made from a shape-retentive material;
one or two conductive coating layers which are electrically conductive and provided by plating on one or both of an inner surface and an outer surface of the waveguide body, for transmitting electromagnetic waves including signals; and
a power line for transmitting electric power other than the signals, th…
